The study of the electronic structure and transport properties of armchair graphene nanoribbons with dopant
摘要
Abstract
The electronic structure and transport properties of armchair graphene nanoribbons ( AG-NRs) with B/N dopant are studied by using the first -principles calculation. It is shown that because of the existence of the dopant, there is an impurity band in the energy gap of armchair graphene nanoribbons and their energy gaps increase. The band structures depend also on the position of the dopant. In addition, the existence of the dopant yields resonant backscattering in the charge transport, whose features are strongly dependent on the types, the position of the dopant and the symmetry of the structure.关键词
