CALDAS, Marília Junqueira
Theoretical study of conventional and/or organic semiconductors, with emphasis on systems of relevance for Si nanotechnology, organic aromatic polymers and hybrid organic/inorganic interfaces. We use many different techniques, for instance empirical force fields for structural properties, and, for electronic structure, from totally empirical methods up to fully ab initio quantum mechanics formalisms within Hartree-Fock or Density Functional theory. When needed, we also move up to Beyond-Mean-Field approaches accounting for electronic correlation effects. At the moment, our main efforts are:
a) For Si nanotechnology, oxidation and functionalization of Si surfaces, and interface formation (Si/SiO2 or Si/organic layers);
b) For organic polymers, we focus on systems of interest to photovoltaics or light emission, including polyphenylene-vinylenes, polythiophenes, polyanilines and others, studying (i) structural properties for amorphous films; (ii) electronic, optical and transport properties for prototypical systems; (iii) polymer/metal and polymer/oxide interfaces.
