Abstract

This proposal aims to enablethe installation of a computational structure which is suitable for development and testingof computer codes and atomistic simulations of nanoscopic systems to bedeveloped at the Physics Department of Unesp in Rio Claro. I intend to continue a study of Nanoscopic Systems that began during a post-doctoral stage occurred betweenAugust/2010 and July/2011 with the group of Professor Douglas Galvãoin IFGW / Unicamp. In the proposed study, it will be investigated the dynamics of the formation, mechanical propertiesand electronic structure of molecular systems containing largenumber of atoms. Structures derived from graphene will be analyzed, with special interest in applications for nanotechnology. For this study, we use well-established tools, such asDensity Functional Theory and Classical Molecular Dynamics methods. Reactive classic force fields like REAXFF will be of major importance in this study, primarilyin calculations of mechanical and tribological properties of graphene, graphane, fluorographene and similar structures.
