Suppression of thermal conductivity in graphene nanoribbons with rough edges
arXiv:1006.4879 · doi:10.1103/PhysRevB.82.195422
Abstract
We analyze numerically the thermal conductivity of carbon nanoribbons with ideal and rough edges. We demonstrate that edge disorder can lead to a suppression of thermal conductivity by several orders of magnitude. This effect is associated with the edge-induced Anderson localization and suppression of the phonon transport, and it becomes more pronounced for longer nanoribbons and low temperatures.
