Effect of Stone-Wales Defects on Electronic Properties of Armchair Graphene Nanoribbons

In this paper, the effects of Stone-Wales (SW)defect on transport properties of armchair graphene nanoribbons (AGNRs) are studied using tight bindingcalculations combined with nonequilibrium Green’s function (NEGF). We evaluate transmission and density of states (DOS) in two cases, pristine and defectiveAGNR, and we compare the results. Our results indicate that in the latter case, a larger bandgap is made due to symmetry breaking in GNR layer
