Alessandro Ricardo of Oliveira is student of the program of master degree of the Polytechnic School of the University of São Paulo, inside of the Group of New Materials and Devices, developing researches about the obtaining, electric doping, properties and applications of fine films of semiconductors of Hydrogenated Silicon Carbide Amorphous (a-SiC:H) obtained by the technique of PECVD (''Plasma Enhanced Chemical Vapor Deposition") . The objective is to give continuity to previous works that they demonstrated the viability and pertinence of a study of this type, approaching aspects that should still be studied better. The activities are developed in the Laboratory of Microeletronic (LME) of the Department of Engineering of Electronic Systems of the Polytechnic School of the University of São Paulo.
