Topologically enhanced nonlinear optical response of graphene nanoribbon heterojunctions

Abstract We study the nonlinear optical properties of heterojunctions made of graphene nanoribbons (GNRs) consisting of two segments with either the same or different topological properties. By utilizing a quantum mechanical approach that incorporates distant-neighbor interactions, we demonstrate th...
