Effects of Thermal Rippling on the Frictional Properties of Free-Standing Graphene.

Abstract

With use of simulated friction force microscopy, we study the effect of varying temperature on the frictional properties of suspended graphene. In contrast with the theory of thermally activated friction on the surfaces of three-dimensional materials, kinetic friction is demonstrated to locally increase with increasing temperature, depending on sample size, scanning tip diameter, and the externally applied normal load. We attribute the observed effect to the thermally excited flexural ripples intrinsically present in graphene, demonstrating a unique case of temperature-dependent dynamic roughness in atomically thin membranes.
