We analyze numerically thermal conductivity of graphene nanoribbons with perfect and rough edges. We demonstrate that edge roughness can suppress thermal conductivity by two orders of magnitude. This effect is associated with the edge-induced energy localization and suppression of the phonon transport, and it becomes more pronounced for longer nanoribbons and low temperatures.

• Thermal properties of graphene and nanostructured carbon materials. (2011, background): “For the ribbons with fixed L =10 nm and width W varying from 1 to 10 nm, K increased from ~1000 W/mK to 7000 W/mK. Thermal conductivity in GNR with rough edges can be suppressed by orders of magnitude as compared to that in GNR with perfect edges [84, 87].”
