Definitions
- This invention relates to polymeric films; more particularly, this invention relates to very thin, highly ordered polymeric films on a substrate; to their preparation, for example, by the
- L-B Langmuir-Blodgett
- amphiphilic organic molecules for example soaps such as neutral or acid calcium stearate
- a substrate for example glass
- L-B technique J. Am. Chem. Soc. 56, 495 (1934) and 57, 1007 (1935)
- Polymeric films may be formed in situ by the L-B technique by utilising, as amphiphilic organic molecule, an unsaturated ester of a fatty acid such as vinyl stearate which is subsequently radiation polymerised, for example by exposure to a -source such as 60 Co. (J. Polym. Sci. Al 10, 2061 (1972)).
- This invention seeks to provide thin ordered polymeric films of improved mechanical and thermal stabilities.
- a process for the preparation of an ordered polymeric film on a substrate which process comprises:
- polymeric film is, from
- X-ray analysis crystalline and, in the case where steps (i) and (ii) above are repeated, has a layered structure.
- amphiphilic is meant herein that the preformed polymer comprises both hydrophobic and hydrophilic pendant groups.
- the reservoir comprises a monomolecular layer of the preformed polymer formed at a fluid phase interface.
- the monomolecular layer is maintained at a constant surface pressure.
- the fluid phase interface is suitably one between a liquid (the subphase) and a gas, vapour or liquid.
- the subphase may be any liquid which is immiscible with, and which will support, the monomolecular layer of the preformed polymer.
- the liquid is preferably an aqueous medium and the gas is air.
- the reservoir comprises a solution of the preformed polymer.
- the solution comprises an organic solvent, for example chloroform.
- the preformed polymer is suitably an organic polymer and, desirably, an organic addition polymer.
- the polymer is thermoplastic and derived from one or more vinyl, vinylene or vinylidene monomers and, for convenience, it is especially preferred that it is a vinyl polymer. it is found to be undesirable to use preformed polymers of too high a molecular weight because the polymer chains become too entangled to give a sufficiently ordered product.
- the molecular weight of the preferred polymer does not exceed that represented by a polymer chain comprising 200 monomer units; desirably less than that represented by a polymer chain comprising 100 monomer units; especially less than that represented by a polymer chain comprising 50 monomer units.
- Suitable hydrophobic groups include hydrophobic heterocyclic groups and unsubstituted or mono- or poly- halo-or hydrocarbyloxy- substituted hydrocarbyi(oxy) groups.
- hydrocarbyl(oxy) is meant herein hydrocarbyl or hydrocarbyloxy. Examples include aryl and aralkyl groups such as phenyl or benzyl and alkyl(oxy) groups such as C 40 to C 4 , preferably C 20 to C 10 , alkyl(oxy) groups such as n-octadecyloxy and n-hexadecyl. It is an important feature of this invention that comparatively short hydrophobic groups may be used, for example phenyl. This is to ensure that, where desired, resulting monomolecular preformed polymeric films may be thin enough to permit quantum mechanical tunnelling.
- hydrophobic groups in the preformed polymer these may be the same or different.
- hydrophilic groups include hydroxyl; poly(ethyleneoxy); pyridyl; N-pyrrolidyl; carboxyl, and precursors which are hydrolysable thereto, for example cyano-, amido-, imido, acid anhydride and acyl chloride.
- hydrophilic groups in the preformed polymer these may be the same or different.
- a mixture of preformed polymers may be utilised. While it is, in general, preferred that each hydrophobic group, or each hydrophilic group, in the or each type of preformed polymer are, for greater ordering, the same (especially each hydrophobic group) it has now been found that one or both may be chemically modified in order to tailor electronic parameters to requirements (especially each hydrophilic group). It is also preferred that, for greater ordering, the preformed polymer is an alternating copolymer.
- preformed polymer which have given satisfactory results include copolymers of an unsaturated acid anhydride, such as maleic anhydride, with a substituted or unsub stituted styrene; a C 12 to C 22 alk-1-ene; or a C 10 to C 20 vinyl ether.
- preformed polymer include poly (n-octadecyl vinyl ether/maleic anhydride); poly(styrene/maleic anhydride) and poly(octadecene-l/maleic anhydride).
- MIS diodes prepared therefrom displayed Schottky barrier heights from 1.1 to 1.5 eV, depending on the mole fraction of anhydride remaining. This is believed to be the first use of an L-B film to produce a MIS device with a Schottky barrier height that can be tailored to requirements.
- the preformed polymer is suitably incorporated as a monomolecular layer at the fluid phase interface by dissolving it in a volatile organic solvent, for example, a volatile hydrocarbon such as hexane, a volatile carboxylic ester, or a volatile halogenated hydrocarbon such as chloroform.
- a volatile organic solvent for example, a volatile hydrocarbon such as hexane, a volatile carboxylic ester, or a volatile halogenated hydrocarbon such as chloroform.
- This solution is then added to the subphase in an amount calculated in known manner (essentially by determining the effective area per molecule from the absorption isotherm and then determining the quantity of solution required to given a monomolecular layer over a known area) to leave, on evaporation, a monomolecular layer. It is preferred that the monomolecular layer is equilibrated for 15 minutes to 4 hours, preferably, 1 to
- a constant surface pressure typically of 20 to 50, preferably 30 to 45, mNm -1 , by means of an adjustable boom, suitably of polyethylene tetrafluoride (PTFE) tape, which confines the monomolecular layer.
- PTFE polyethylene tetrafluoride
- the process of the present invention is applicable to a wide variety of substrates, preferably inorganic and metallic substrates, including glasses such as aluminosilicate glasses, optical materials of appropriate refractive index and surface smoothness, for example fused quartz, metals such as aluminium, chromium, nickel, brass, steel, cast iron, silver, platinum or gold, metal oxide layers on aluminium or tin, plastics such as polystyrene, poly(ethylene terephthalate), cellulose acetate or polypropylene plastics and, in accordance with one particularly preferred aspect of this invention, semiconducting materials, for example silicon single crystals; amorphous silicon; III-V compounds such as BN, BP, AlSb, GaN, GaP, GaSb, GaAs, InP, InSb, InAs, preferably GaP, GaAs and InP; II-VI compounds such as CdS, CdSe, CdTe, ZnO and ZnS, preferably CdS and CdTe;
- the substrate may be superconducting material, for example a superconducting metal, or a superconducting alloy thereof, of Groups IIIA, IVA, VA, VIIA, VIII, IIB, IIIB or IVB of the Periodic Table, such as Nd, Ti, Zr, Hf, Th, V, Nb, Ta, Rh, Ru, Os, Zn, Cd, Hg, Al, Ga, In, Tl, Sn, Pb, preferably Nd, Nb, and Sn including the compound Nb 3 Sn.
- the substrate may need preparation in known manner prior to coating; for example, silicon may need to be etched and it may need to have a thin coating of oxide formed thereon.
- the substrate is advanced though the reservoir of preformed polymer in known manner, for example by being coupled to a simple variable speed motor, typically at a speed of 0.5 to 50, preferably 1 to 10, mm.min -1 .
- the substrate may, depending (it is believed) on whether it is wetted on only one or both the advancing and recovering operations accrete one (X-mode) or two (Y-mode) ordered polymeric films. The advancing and recovering operations may be repeated, if desired, to build up thicker ordered films.
- Monomolecular preformed polymeric films prepared in accordance with this invention may have a thickness less than 50 ⁇ , preferably no greater than 20 ⁇ , especially no greater than 10 ⁇ . Where the evisaged use does not depend on quantum mechanical tunnelling it may be desirable to prepare thicker, multilayer preformed polymeric films; for example, in optical devices a thickness of 1 mm to l ⁇ may be required.
- the coated susbstrate When the final recovering operation has been effected it is desirable to dry the coated susbstrate, suitably overnight, in helium or nitrogen.
- An electrode for example 50 ⁇ to 1000 ⁇ of Au, can then be evaporated thereon at a temperature from ambient temperature to -100°C. It is then desirable to give the dried coated substrate onto which coating an electrode has been evaporated (that is, a device in accordance with the invention) an annealing treatment in which it is maintained, typically for 1 to 24 hours, for example 2 to 4 hours, at a temperature from ambient temperature to 200°C, preferably above 50°C, typically from 100° to 180°C, such as 150°C which is believed to enhance the ordering of the polymeric film.
- Semiconducting devices in accordance with this invention include MIS devices wherein (with reference to Figure 1 of the accompanying drawings) a semiconductor substrate 1 is provided with a contiguous ordered preformed polymeric film 2 on the other surface of which an electrode 3 is deposited.
- MIS devices wherein (with reference to Figure 1 of the accompanying drawings) a semiconductor substrate 1 is provided with a contiguous ordered preformed polymeric film 2 on the other surface of which an electrode 3 is deposited.
- Examples of the use of such devices include Schottky barrier MIS diodes, Schottky barrier tunnel diodes, and Schottky barrier MIS capacitors (which differ essentially by comprising progressively thicker preformed polymeric films).
- Specific examples include solar cell and electroluminescent devices (which are both Schottky barrier MIS diodes).
- FETs wherein (with reference to Figure 2 of the accompanying drawings) a semiconducting substate 4 is provided with source and drain electrodes 5 and 6 and a contiguous ordered preformed polymeric film 7 interposed between the electrodes as a gate insulator and carrying a gate electrode 8.
- the insulator 7 is of a suitable nature (namely, that it is capable of reversible or irreversible binding of substances which, when bound, alter the electrical properties of the FET) the FET can give a detector response, inter alia, to gases, ions, and organic molecules including immunogens.
- MIM devices in accordance with this invention include tunnel junctions such as Josephson junctions wherein (with reference to Figure 3 of the accompanying drawings) a superconducting substrate 9 is provided with a contiguous ordered preformed polymeric film 10 on the other surface of which a further superconducting layer 11 is deposited.
- the interposed film 10 must be less than 50 ⁇ . At temperatures of about 3°K superconducting current may pass through the device by a tunnelling mechanism dissipating no device power and enabling their use as ultra high speed devices, for example in computer memories.
- Figure 4 is a schematic side elevation of the Langmuir trough apparatus used in this invention.
- Figures 5 to 7, inclusive, are schematic plans of the trough of Figure 4 showing detail of the constant perimeter design.
- Two moveable, wax-coated brass barrier supports 3 and 4 are each supported by two pairs of PFTE diabolo-shaped wheels 5 which seat on two stainless steel rods 6 which are aligned generally parallel at the sides of the trough; and are each lockable onto two rubber drive belts 7 and 8 which are aligned generally parallel and in a vertical plane at either side of the trough.
- Each moveable barrier support carries two pairs of PTFE capstans 9, 10, 9' and 10' which project downwardly into the trough.
- a moveable, wax-coated brass bridge 14, spanning the trough, is mounted on parallel rails 15 which run at either side of the trough and carries an axially aligned micrometer screw 16 linked to a substrate holder 17.
- a Cl balance head 18 supports a surface pressure sensor 19. The apparatus described above, with the exception of the balance head which is mounted thereon, is enclosed in an anodised aluminium glove box (not shown) having a perspex window.
- the tank Before use, the tank is subject to a thorough cleansing regime: it is first washed with concentrated nitric acid, next with chloroform, then ethanol and finally rinsed with distilled water. The tape barrier and the capstans are wiped with isopropyl alcohol and assembled. 2.51 of fresh, premixed subphase (see the following Example for formulation details) are than poured into the tank and the pH is adjusted by addition of small amounts of hydrochloric acid or sodium hydroxide. The surface of the subphase bounded by the barrier is next sucked clean with a micropipette- terminated filter pump (not shown)and a film is spread with a micropipette (Finipipette).
- the process is repeated until no discernable change between adjacent clean subphase readings is observed on the balance when the barrier supports are rapidly mutually reciprocated.
- the Langmuir film is then carefully spread on the subphase using about 200 - 400 1 of a solution of preformed polymer (see the following Examples for formulation details) by a micropipette; and left for a period from 30 minutes to 4 hours to equilibriate.
- the film is slowly compressed and expanded twice or three times. in use, the film is slowly compressed by moving the barrier supports 3 and 4 together by actuation of drive belts 7 and 8 by means of a Maxon 2332.908 DC motor with attached series 69 gearbox (1:400 ratio) (both not shown).
- the surface pressure of the film is continuously monitored by the balance 18 and the output is fed into a differential feedback circuit (not shown) linked to the motor which is then driven to maintain a constant surface pressure.
- the substrate holder 17 is moved down through the film by driving the micrometer screw 16 with a Maxon 2325.913 DC motor with attached series 27 gearbox (1:500) (both not shown) to give a substrate speed of 1 to 25 mm min -1 , generally 4 mm min -1 . After immersion, the substrate is then driven up through the film.
- each monolayer is first dried for 4 hours before repeating the above sequence.
- the final film is stored for a period from 1 to 5 days under dry nitrogen in a dissicator before top electrode evaporation.
- the barrier support movement may be monitored by measuring the resistance of a 10-turn potentiometer (Phillips DM2517E multimeter) linked to the geared drive (both not shown) of the drive belts 7 and 8. From the change in reading per turn of the micrometer screw 16, the deposition ratio (DR) can be calculated where:
- EXAMPLE Metal substrates were prepared in the following manner: "Chance Select" microscope slides (70 mm x 26 mm x 2 mm) were used as a base for thin, evaporated metal films. They were initially inspected for scatches, imperfections, grease or dust and discarded if necessary. They were then wiped clean, with a fibre-free tissue soaked in methanol, and sonicated in chloroform prior to overnight storage in isopropyl alcohol (IPA). Some slides were flame-smoothed, a process which gives a smoother surface, and recleaned. Before use the stored slides were boiled in IPA and then in distilled, deionized Millipore filtered water.
- IPA isopropyl alcohol
- the metal evaporations were next carried out in an Edward's Model 306 Vacuum System, using a standard oil diffusion pump and nitrogen trap. The system was capable of achieving a pressure of 2 x 10 -7 Torr, but the evaporations were routinely carried out at 10 -1 Torr. Prior to evaporation the sample was concealed behind a mask and the source preheated above the evaporation temperature to drive off any organic contaminant. The sample was then exposed and the rate of deposition and final film thickness monitored on an Edwards Quartz Crystal Film Thickness Monitor. Aluminium evaporations were normally carried out at 15 cm from tungsten wires at rates of ⁇ 0.5 nm s -1 to give a final film thickness of 30 nm.
- the aluminium On exposure to air the aluminium rapidly oxidised to a depth of about 2.5 nm. Tin was more difficult to use; when evaporated slowly the film was heavily stressed and developed surface spikes. Films less than 100 nm thick exhibited considerable series resistance, attributed to the grain boundaries in the film. Good films were obtained by evaporating at rates > 10 nm s -1 at 10 cm range from tantalum or molybdenum boats. After a few evaporations the tin alloyed with the metal boat and the evaporation rate fell markedly - it was necessary to use new boats every 2-3 evaporations. 200 nm thick films were produced, which often appeared a milky-white colour. Oxidation in air proceeded rapidly to a depth of about 2.3 nm.
- Cleanliness of evaporator was important in achieving consistently good quality films.
- the evaporator was regularly cleaned with sodium hydroxide to remove the metal films deposited on the inside of the chamber during evaporations.
- Semiconductor substrates were prepared in the following manner:
- the substrate comprised single crystal n + -GaP slices which were ⁇ 100> oriented and polished on one side (ex Cambridge Instruments Ltd.).
- the sulphur dopant concentration was 3.5 to
- the slices were precleaned in boiling chloroform and sonicated in isopropanol before etching in a two-stage procedure: (i) 3 minutes in H 2 SO 4 :H 2 O 2 :H 2 O in the volume ratio 4:1:1; (ii) 1 minute in H 2 O 2 :H 2 O in the volume ratio 1:20 containing 2 g of NaOH per
- a glass Langmuir trough having dimensions and filiments as hereinbefore described was filled with 2,500 ml of distilled deionised Millipore filtered water containing 2.5 x 10 -4 M aqueous
- Poly(octadecene-l/maleic anhydride) films were allowed to equili briate only for 30 minutes to minimise hydrolysis; partial hydrolysis was effected by equilibriating for 5 hours; and the free acid was prepared ab initio by reactions with 1M NaOH followed by precipitation with HCl. (The latter was spread as a solution in ethyl acetate; there was no need to equilibriate longer than 30 minutes.)

- Figure 9 is a graph of bias voltage (V) versus log e J(A cm -2 );
- Figure 10 is a Fowler plot; and Figure 11 is a graph of bias voltage (V) versus reciprocal
- the preformed polymer films produced in accordance with this invention have improved mechanical and thermal stability; devices comprising them can be baked to 200°C and not only remain intact but also have greatly improved properties; for example, electrical resistance can be increased by up to 10 3 X.
- Schottky barrier heights of devices of this invention can be precisely tailored to requirements.
- the process offer means of imparting insulator films onto semiconductors, such as GaP and GaAs, which are not readily or usefully oxidised.
