Research and development of new materials of interest in nanotechnology: applications in (micro-) electronics and metal-mechanics industries

Abstract

The aim of the project is the experimental and theoretical study of the fundamental electronic, optical, structural, and mechanical properties of new, micro and/or nanostructured materials, for electronic applications as well as promotes their use in technological applications. The materials will be obtained by Dual Ion Beam Assisted Deposition, Chemical Vapor Deposition, Sputtering, Arc Discharge, Laser Evaporation, and Pulsed Plasma. Materials like SiC, TiN, a-Ge and a-Si doped with rare earth, hard coatings, and metal alloys treated by nitrogen implantation. These goals are intimately linked to the scientific tradition of our research group and with the current graduate student programs at both the Instituto de Física "Gleb Wataghin" and the Instituto de Física da Universidade de São Paulo (São Paulo e Sao Carlos). Therefore, the training of student at the three levels, i.e., scientific training for under-graduate students, Master and PhD students, is of fundamental importance to the proposal. To reach these goals, we shall take advantage of our past experience and the existence of modem experimental facilities such as photoemission electron spectroscopy (XPS, UPS), X-ray diffraction, visible and infra-red optical absorption, nano-hardness, electron microscopy (TEM and SEM), field emission, Ramal1, and others. The project also considers the upgrading and renewing some experimental facilities. We shall continue the studies of materials such as diamond like (amorphous) carbon DLC, CNx, SiCx, SiNx, TiN, AIN, etc. related to their structural, electronic, optical, and mechanical properties. A theoretical effort to understand the structural properties will be done based on modem quantum chemical techniques and compared with the experimental results. Experimental conditions leading to the improvement of the properties of the studied materials will be pursued. Finally, a strong interaction with the local industry will be a priority of the project with the purpose of technological transference. (AU)
