Abstract
The method of doping diamond using charge transfer from organic dyes is characterized by an organic dye is covalently bonded on diamond and exposed to irradiation with light. The covalent bond can be formed during an electrochemical oxidation of the organic dye in a solution with the hydrogen-terminated diamond serving as an anode. The bonding process can be confined to predefined areas if the hydrogen-terminated area is spatially localized using insulating mask or selective oxidation. Both natural and synthetic diamond on various substrates can be used. The concentration of impurities in diamond is not limited.
Description
Method of doping diamond using charge transfer from organic dyes
Technical field
The invention relates to doping of semiconductors and optoelectronics.
Background art
Diamond belongs among relatively new semiconducting materials. It represents a unique combination of excellent semiconducting, mechanical, chemical and biological properties. Being a semiconductor with wide band-gap (5.5 eV), it serves as a very good insulator when in intrinsic state. When doped with impurities (boron, phosphorus), however, both p-type and n-type conductivity can be obtained. Its wide band-gap makes it transparent in the optical region, which is of great importance for optical applications. Moreover, a two- dimensional layer with high conductivity is formed on hydrogen-terminated diamond surface. Diamond exhibits photoconductivity, intriguing behavior of excitons and other attractive properties for optoelectronic applications. Furthermore, being very hard and mechanically, chemically and physically stable with an unusually wide electrochemical window (>3V), in which the surface does not chemically react itself but supports chemical reactions, it is also advantageous material for electrochemical measurements and applications. As it is made up of carbon, it is considered highly biologically compatible. Eventual applications in prosthetics and biosensors are being intensely studied. Diamond can be synthetically prepared both as a bulk material and in the form of thin layers on various types of substrates using methane decomposition in plasma discharge.
As a result of the above-mentioned properties, the use of diamond in electrochemistry as both a passive and active interface for various organic and biological materials starts to be of great importance. New devices in the fields of chemical sensors, biological sensors, micro- and optoelectronics are being developed, an example of which can be the use of diamond as a substrate for optical and electronic sensors of DNA, which can covalently and stably bond to diamond. When compared to diamond, chemical bonds of organic molecules with commonly used materials such as silicon, silicon oxide or gold are significantly weaker, which leads to gradual degradation of these interfaces in time, in contrast to the diamond-based ones.
When it comes to active electronic devices, high, nearly two-dimensional surface conductivity of otherwise non-doped diamond is of particular interest. The generation of free charge carriers is caused by the transfer from external environment or surrounding material, which allows for a very easy fabrication of electronic circuits. This mechanism is of a particular interest for a further decrease in size of various electronic elements, as the decrease starts to be limited by the concentration limits of dopants in the bulk material. It is the contact between diamond and the electrolytic solution which primarily gives rise to the surface conductivity. Such surface conductivity based on an electrolytic system is problematic, however, due to its fluctuations when exposed to external environment. Another, recently discovered way to produce surface conductivity consists in the deposition of a continuous layer of fullerenes onto hydrogen-terminated surface of diamond, which makes it possible to generate surface conductivity by the transfer of charge from the solid phase without the influence of the external environment. Nevertheless, the surface conductivity of fullerene- coated diamond is still thermally and mechanically unstable, since the fullerenes are attached to the surface only by adhesion. The possibility of using other organic materials is still being investigated, but other methods to generate surface conductivity have not been published so far.
Disclosure of the invention
The present invention provides a method to overcome the above-mentioned drawbacks and meet the requirements through the chemisorption of an organic dye on diamond. The said organic dye serves as a source of electrical charge for diamond. Organic dyes are macromolecules or polymers with a conjugated system of electrons, which is both optically and electronically active and, moreover, mechanically and chemically stable. Consequently, their advantageous properties, both chemical (sensitivity of electric conductivity to acidity of the environment, possibility of bonding with biological molecules) and optoelectronic (e.g. in organic displays, photovoltaic cells, storage media, dyes) are being exploited. In the present time, light-emitting diodes or field transistors based on organic materials keep up with, or even outperform devices based on inorganic materials. Polypyrrole or polyaniline can serve as a representative example of such dyes. These dyes can be easily prepared by electro- polymerization from aqueous solutions, during which electrically conductive and chemically stable conjugated chains with optical absorption in the visible region of the electromagnetic spectrum are formed.
Hydrogen-terminated diamond is used for this type of doping. Organic dye covalently binds to this modified diamond surface and then it is exposed to irradiation with light. For example, diamond can be immersed in a solution containing radicals of the organic dye, or, as another possibility, in an electrolytic solution containing a monomer of the organic dye. In the latter case, diamond serves as an anode and a cathode is put into the solution, which results in the synthesis of the polymer on the surface of diamond by electrochemical oxidation. Being an anode, the surface of diamond is biased positively with respect to the solution. The cathode can be made of any material (including diamond), while polypyrrole or polyaniline can be used as the organic dyes.
The area with hydrogen-termination on the diamond surface can be patterned using an electrically insulating mask or selective oxidation of the surface. The diamond itself can be prepared by chemical vapor deposition in microwave plasma, can be doped or intrinsic, or even of natural origin.
Example
Synthetic, nominally undoped monocrystalline diamond prepared by chemical vapor deposition is used. Diamond is cleaned by boiling in a mixture of acids (H2SO4H-KNO3, ratio 3:1) at 200 °C for 30 minutes, rinsed with deionized water and dried with a flow of dry nitrogen. Afterwards, the sample is treated in oxygen high-frequency plasma with the output of 300 W for 3 minutes. Then, the surface of diamond is terminated with hydrogen by exposing it to hydrogen plasma at 800 °C for 10 minutes at the pressure of 3000 Pa, gas flow of 5xlO"6 m3/s and output of the plasma generator of 1100 W. This treatment yields clean and well-defined hydrogen-terminated surface of diamond, which is highly hydrophobic (wetting angle ~ 90°). A gold electrode is deposited onto a part of the diamond's surface using thermal evaporation.
Polypyrrole chains are then bonded on the hydrogen-terminated diamond surface by immersing it in a solution of the monomer (pyrrole) with the concentration of 0.24M and salt (NaCl) with the concentration of 0.1 M in deionized water. The diamond serves as an anode, while platinum is used as a cathode. Electrochemical oxidation takes place at the constant current of -0.3 mA/cm2 for about 1 minute. When the deposition is finished, diamond with the polypyrrole layer is rinsed with deionized water and dried with a flow of dry nitrogen.
Irradiation of the diamond with white light (illuminance of 1-400 lux) is used to induce the charge transfer. Various spectral regions of the white light can be applied, with the highest efficiency in the blue region.

The above-described method for doping of diamond by charge transfer from organic dyes is aimed at the fabrication of electronic and optoelectronic devices, optoelectronic transducers, chemical and biological sensors and actuators, localized chemically and electronically active spots on the diamond surfaces, etc.
