Abstract
The non-equilibrium Green's function method was employed to investigate the pressure effects on the interfacial thermal resistance of few-layer graphene. It is found that a compressive pressure of 10 GPa along the cross-plane direction can reduce the interfacial resistance by approximately 4 times, when compared with no applied pressure. As pressure is applied along both in-plane and cross-plane directions, the effects of the in-plane direction pressure on the cross-plane thermal transport are much weaker than those of the cross-plane pressure. Our results indicate that the interlayer interfacial thermal resistance of graphite can be modulated to a large extent by external pressure.
