Strain Manipulation for Transport Properties for Armchair-Edge Graphene Nanoribbons ——Under a Small Strain
摘要
Abstract
Electronic transmission coefficients and density of states for uniaxially small strained armchair- edge graphene nanoribbons (AGNRs) are demonstrated by the first-principle calculations based on non equilibrium Green's function method and density-functional-theorem. It is observed that the system den sity of states and transmission coefficients of semiconducting AGNRs are sensitive to the external uniaxi ally small strain,while the energy gaps of metallic AGNRs may be opened under a small strain.关键词
