Abstract

The research topic of this project - the design, fabrication and characterization of nanostructured thin films fabricated with methods of "soft chemistry" - for flexible and/or printable electronics, mobile, using low power operation - is booming, which should produce patents and scientific publications of high impact, helping to increase the competitiveness of research and visibility of the São Paulo State University and Francophones (Universidade Federal de Minas Gerais and Polytechnique Montreal) in the field of advanced materials. From an experimental point of view, the project provides for the deposition of thin. layers (prof. Orlandi) on micro fabricated substrates (prof. Santato) and characterization (at their interfaces with the electrodes and substrates) of morphological / structural type (prof. Orlandi), Electrochemical (prof. Santato) and Electronic / Optical (Prof. Gonzales). The project will offer our future students a unique multidisciplinary environment that will allow them to progress in various professional aspects and very internationally competitive atmosphere. The quality of education will be enhanced by access possessed by the highly trained staff in international exchanges, with visits from partners. (AU)
