Scattering of Graphene Plasmons by Defects in the Graphene Sheet [PDF]
A theoretical study is presented on the scattering of graphene surface plasmons by defects in the graphene sheet they propagate in. These defects can be either natural (as domain boundaries, ripples and cracks, among others) or induced by an external gate.

Graphene–Graphene Interactions: Friction, Superlubricity, and Exfoliation [PDF]
AbstractGraphite's lubricating properties due to the “weak” interactions between individual layers have long been known. However, these interactions are not weak enough to allow graphite to readily exfoliate into graphene on a large scale. Separating graphite layers down to a single sheet is an intense area of research as scientists attempt to utilize ...
