Thermal Transport in Graphene, Few-Layer Graphene and Graphene Nanoribbons

Abstract: The discovery of unusual heat conduction properties of graphene has led to a surge of theoretical and experimental studies of phonon transport in two-dimensional material systems. The rapidly developing graphene thermal field spans from theoretical physics to practical engineering applications. In this invited review we outline different theoretical approaches developed for describing phonon transport in graphene and provide comparison with available experimental thermal conductivity data. A special attention is given to analysis of the recent theoretical results for the phonon thermal conductivity of graphene and few-layer graphene, the effects of the strain, defects, isotopes and edge scattering on the acoustic phonon transport in these material systems.
