• Abstract

  This project wants to renew the research topics of the Laboratório de Filmes Finos (IFSC-USP) through the improvement of its experimental facilities. Within the topics under consideration one should mention: (a) the systematic investigation of thin films containing rare-earth or transition-metal species - aiming at the development of novel luminescent materials, broad-band light sources...

• Abstract

  The main goal of this project is to study the crystallization mechanisms induced by high hydrostatic pressures. The systems to be investigated are micro- or nano-structures embedded in amorphous inorganic semiconductors (a-Si and a-Ge), oxygen- (a-SiOx and a-GeOx) or nitrogen-containing (a-SiNx and a-GeNx) matrices. They will be prepared in the form of thin films under three different w...

• Abstract

  This research program focuses on the systematic investigation of ruby (or Cr-doped aluminum dioxide) microstructures. Within that context, films of aluminum-nitrate (AlN) containing chromium species will be prepared by cosputtering and submitted to thermal annealing treatments in an atmosphere of oxygen. Recent investigations conducted in our laboratory have shown that, under these cond...

• Abstract

  The main purpose of this short-term research program is the investigation of Si-based materials by means of high-resolution experimental techniques. The target samples, prepared in the form of thin films, will consist of SiN alloys doped with rare-earth ions and Si films containing Ni or Fe species. The program will start with some basic characterization (essentially optical and composi...
