Receiving and research of thin films of graphite and oxide of aluminium as bases for high capacitance capacitors

Abstract

Receiving nano-carbon, in particular, graphitic films of nanometer thickness and research of their properties is one of current problems of the modern science. Structural characteristics of such materials lead to origin of a row of unique features in their physical properties which can be used for creation of new types of electronic and optic instruments and devices. One of perspective forms of application of thin graphitic films can read use them as capacitors plate. Now the main type of the rechargeable batteries which are widely used in different areas, electrochemical sources are. At the same time row of their shortcomings, somehow: complicates their application, for example, in electric vehicles and different robotic devices. One of possible solutions of the matter, use of energy «collected» condensers is. At the same time it is possible to have the almost instantaneous charging and an opportunity of monitoring and control behind time and power of discharge. However application as similar power supplies of condensers of «traditional» construction does not allow receiving rather high capacity. Use as plates of the condenser of materials with minimum possible size of particles can be one of possible candidate solutions of the matter. As those the electrodes consisting of the thin carrying-out films on the basis of the particles of graphite applied on the transparent substrates can be used, for example. However in order that graphitized electrodes could be used in practice, they shall meet certain requirements. First of all to have high conductance, to be the transparent in optical band that is necessary for monitoring of thickness and in general structure of films by spectral methods. And, at last, they shall be steady against mechanical influences. Proceeding from the above, the real operation is devoted to receiving and a research of thin films of graphite and aluminum oxide as perspective materials for creation of high capacitance capacitors.
