Electromechanical Properties of Suspended Graphene Nanoribbons
Graphene nanoribbons present diverse electronic properties ranging from semiconducting(1-3) to half-metallic,(4) depending on their geometry, dimensions, and chemical composition.(5, 6, 7) Here we present a route to control these properties via externally applied mechanical deformations. Using state-of-the-art density functional theory calculations combined with classical elasticity theory considerations, we find a …
