  Two-dimensional materials, such as graphene, boron nitride and transition
metal dichalcogenides, have attracted increased interest due to their potential
applications in electronics and optoelectronics. Thermal transport in
two-dimensional materials could be quite different from three-dimensional bulk
materials. This article reviews the progress on experimental measurements and
theoretical modeling of phonon transport and thermal conductivity in
two-dimensional materials. We focus our review on a few typical two-dimensional
materials, including graphene, boron nitride, silicene, transition metal
dichalcogenides, and black phosphorus. The effects of different physical
factors, such as sample size, strain and defects, on thermal transport in
Two-dimensional materials are summarized. We also discuss the environmental
effect on the thermal transport of two-dimensional materials, such as substrate
and when two-dimensional materials are presented in heterostructures and
intercalated with inorganic components or organic molecules.
