Propriedades eletrônicas de nanofitas de grafeno sob efeito de cisalhamento simples e campo elétrico

Abstract

This work intends to study the electronic properties of graphene and graphene nanoribbons of the type AGNR and ZGNR, using the Tight-Binding method in the second quantization formalism to first atomic neighbours. First of all, we analyze the case in which a graphene nanoribbon experiences a simple shear stress. After, we observe the effect that arises when we apply a constant eletric field on graphene nanoribbons AGNR and ZGNR, where the eletric field is parallel to the discrete direction of the nanoribbon. Finally, we consider both perturbations at once (simple shear stress and constant electric field) and compare the result with the effect produced by the perturbations separately.
