Theoretical study of bidimensional systems

Abstract

We are studying several molecular systems with potential technological applications. We have started some studies of systems analogous to graphene and its inorganic derivatives, where pairs of C atoms are replaced by B and N atoms and also by B and P. More recently, we have started studies on carbonic structures based on the azulene molecule. These structures are: polymers, 2-D structures, usual and Möbius nanowires, nanotubes, nanotubes, structures decorated and replaced mainly by BN pair. We also intend to study the behavior of graphene and derivatives BN and BP in the presence of charges or ions and to verify if the "graphene" sheet could be curved in the presence of ions or even "wraps" them. We started the work by studying the coronene submitted to an electric field due to two punctual charges. We will use finite graphene models (coronenos and super-benzenes) to study the folding of graphene under electric field due to two charge points located on opposite sides and perpendicular to the plane of the graphene.In general, the methodology is based on DFT level calculations, states with several multiplicities, or more sophisticated (MP2 or CC2), when possible.
