  • copper thiocyanate layers a p-type semiconductor material, are produced by various methods.
  • CuSCN layers are deposited in an aqueous basic (pH ⁇ 9) solution, which results in Journal of the American Ceramic Society, vol. 90, 2007, pp. 2966-2973 is described. Also by means of electrodeposition, a CuSCN layer is deposited on a porous TiO 2 - layer and fills the pores of this layer completely, as in WO 00/52764 A1 described.
  • H54-H57 describes the preparation of a transparent CuSCN layer by means of thermal vapor deposition first of a Cu layer, then a KSCN layer and subsequent reaction of both layers in a drying vessel with silica gel as drying agent for up to 24 hours. Depending on the reaction time, the transparency of the resulting CuSCN layer is improved.
  • a CuSCN layer in a saturated solution of CuSCN and dipropyl sulfide is deposited on a preheated to 80 ° C sample of the structure glass / SnO 2 : F / ZnO sp / ZnO ed / CdSe.
  • the CuSCN layer fills the nanostructured ZnO layer.
  • DE 101 42 913 A1 describes a transistor arrangement in which the microholes of a composite film, consisting of two plastic films with intermediate metal layer, vertically filled with p-type CuSCN by means of chemical bath deposition. Further details on the parameters of the deposition are not mentioned here.
  • the object of the invention is therefore to provide a further method by means of chemical bath deposition thin transparent nanocrystalline CuCSN layers, which is inexpensive, works well on non-conductive substrates and without seed layer and no toxic solvent needed.
  • the object is achieved in that in the chemical bath deposition according to the invention first the surface of the substrate is activated and then the substrate and the aqueous solution are adjusted to different temperatures, the temperature of the substrate is set higher than the temperature of the solution, and an aqueous Solution with 0.1 to 200 mM Cu (II) - and SCN ions is used, and the substrate is bathed by this bath solution.
  • the substrate / the substrate surface is heated to a temperature between 5 and 200 ° C and the aqueous solution is maintained at a temperature between 0 ° C and 100 ° C.
  • concentration of the Cu II and SCN ions is adjusted so that the aqueous solution is metastable and little or no CuSCN precipitates.
  • ion sources the state of the art is known for CuS0 4 and KSCN.
  • the Cu (II) and SCN-ion solution can also be prepared at temperatures of 0 to 25 ° C from prediluted solutions with thorough mixing to the stability of the bath solution increase and avoid early precipitation of CuSCN.
  • other water-soluble copper and thiocyanate ion sources can be used, such as copper (II) acetate, cupric chloride, ammonium thiocyanate or sodium thiocyanate.
  • Both the morphology of the Cu (I) SCN layers and the nature of the crystal phase ( ⁇ - or ⁇ -CuSCN) is determined by the Cu (II) and SCN initial concentration, the temperature gradient between substrate and solution, the surface-active additives and Badkonvetation affected.
  • a non- or bad conductive substrate can be used, for example, silicon or glass or a polyimide film.
  • silicon or glass or a polyimide film On substrates with high thermal conductivity and heat resistance higher deposition rates can be achieved.
  • the process according to the invention does not use expensive organic, partly toxic solvents (eg acetonitrile or dipropylsulfide) as in the "impregnation" method and, compared to the sequential SILAR technique, higher deposition rates can be achieved.
  • expensive organic, partly toxic solvents eg acetonitrile or dipropylsulfide
  • PEG polyethylene glycol
  • SLS sodium lauryl sulfate
  • the application of such a CuSCN seed layer to the substrate can influence the morphology of the CuSCN layer to be subsequently deposited.
  • the substrate A to be coated is in the in FIG. 1 installed schematically illustrated cell.
  • the flow cell B consists of polyether ketone (PEEK) and a Viton O-ring C.
  • the bath D flows through the chamber has dimensions of about 14 mm wide, 17 mm long and 1.5 mm high.
  • the heater E consists of an aluminum block (60 mm width, 70 mm length and 10 mm height), which is held by four electric heating elements (each 60 W power) by means of a PID controller at a constant temperature (T heating ).
  • the bath supply vessel with a volume (V total ) is mixed by means of a magnetic stirrer, via a temperature sensor, the bath temperature (T bath ) is monitored and optionally controlled by a thermostat.
  • the inlets and outlets F of the cell are connected to a storage vessel via a peristaltic pump , which regulates the volume flow (v pump ) of the bath. Furthermore, the process is characterized by the deposition time ( t deposition ).
  • the substrates are each degreased for 5 minutes in 3% Mucasol solution in an ultrasonic bath, then rinsed with tap water, deionized water and isopropanol and dried in a stream of nitrogen.
  • reaction solutions are prepared from prediluted solutions of CuSO 4 and KSCN with vigorous stirring at the lowest possible temperature to minimize precipitation of Cu (I) SCN.
  • the substrate heating is switched on and only when the target temperature is reached, the solution is pumped through the flow cell and the deposition begins. At the end of this, the substrate heater is turned off, the heater block is actively cooled with water, and the cell is rinsed with 20 ml of deionized water. Subsequently, the substrate is removed from the cell and rinsed again with deionized water and isopropanol and dried in a stream of nitrogen.
  • the parameters are varied during the coating of a Si substrate in four variants.
  • a 0.4 mm thick Si substrate is introduced into the cell.
  • the heating is set to 150 ° C, thus increasing the bath temperature from 20 ° C to 98 ° C in the described arrangement.
  • the duration of the deposition is set to 10 min.
  • the sample is covered with a fine-crystalline CuSCN film about 1.5 ⁇ m thick, as in Fig. 2 recognizable.
  • the Si substrate is now placed in a bath solution containing 10 g / l PEG200 in high concentration, the bath temperature is thereby increased from 18 ° C to 38 ° C and carried out the deposition over 180 min.
  • the result is a very inhomogeneous deposition of large crystallites predominantly in the ⁇ -Cu (I) SCN modification.
  • aqueous bath solution SLS is added in a low concentration of 0.2 g / l and only a deposition time of 10 min is carried out (Variant IV ) , only a very thin layer ( ⁇ 200 nm) of hexagonal crystals grows on the Si substrate, but not yet formed closed.
  • the heating temperature T heating is 95 ° C, the temperature of the chemical bath rises from 18 ° C to 38 ° C with active cooling.
  • the chemical bath solution was rinsed over the Si substrate for 180 minutes. As a result, a very homogeneous deposition of very large crystallites was observed predominantly in the ⁇ -Cu (I) SCN modification, as in Fig. 5 recognizable.
  • a CuSCN layer is applied to a 1.0 mm thick soda-lime glass.
  • the bath was then pumped through the cell at 5.4 l / h and heated from 20 ° C to 88 ° C over a period of 120 min by means of additional heating. After completion of the deposition process, the surface of the soda-lime glass is covered with an about 4 .mu.m thick Cu (l) SCN film, as in Fig. 6 shown. According to XRD analysis - s. FIG. 7 All peaks can be assigned to the ⁇ - or ⁇ -CuSCN modification.
  • a conductive substrate is used and a CuSCN layer is applied to a 1.0 mm thick aluminum substrate.
  • the deposition takes place at a heating temperature of 150 ° C.
  • the bath temperature rises from 20 ° C to 100 ° C.
  • the hot Al substrate is rinsed with the bath solution for 5 min.
  • On the sample grows a microstructure, which consists of large platelet-shaped crystallites (s. Fig. 8 ).
  • the XRD analysis of the grown-up layer yields maxima which are attributed to the ⁇ - and - the predominant - ⁇ -CuSCN modification as well as the aluminum of the substrate.
  • the bath temperature rises from 20 ° C to 70 ° C at a heating temperature of 160 ° C.
  • the sample is lapped for 10 minutes by the bath solution, this process is repeated again.
  • the polyimide film is overgrown at the edges with a CuSCN layer of the ⁇ - and ⁇ -CuSCN modifications, but only sporadic crystal growth is observed in the center of the film.
  • Fig. 9 shows an SEM image of only the edge region of the sample with a dense growth of a CuSCN layer.
  • the exemplary embodiments prove that the method according to the invention, using chemical bath deposition, makes it possible to deposit thin transparent CuSCN layers on different substrates.
