摘要	Y Atomic thickness two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted intensive attention due to the potential application for next generation nano-electronic devices. The thermal properties of materials play a vital role in performance of nano-electronic devices. Here, few-layered MoS2/reduced graphene oxide (RGO) heterostructure with intimate two-dimensional heterointerfaces was successfully synthesized via hydrothermal method. We report for the first time the temperature-dependence Raman vibration of few-layered MoS2/RGO hybrid. The temperature coefficient of A(1g) modes in few-layered MoS2 solely and MoS2/RGO hybrid are -0.0141 and -0.0154 cm(-1)/K, respectively. The Raman vibration of E-2g(1) and A(1g) modes with laser powder increasing in the two samples were also measured. The qualitative analysis and comparison of the two samples suggested that the few-layer MoS2 in MoS2/RGO hybrid possesses higher thermal conductivity than few-layer MoS2 solely.
