Thermal transport in MoS2/Graphene hybrid nanosheets

摘要: Heat dissipation is a very critical problem for designing nano-functional devices, including MoS2/Graphene heterojunctions. In this paper we investigate thermal transport in hybrid nanosheets under various heating conditions, by using molecular dynamics simulation. Diverse processes and characteristics, depending on the conducting layers, are found these structures. The conductivities can be tuned interlayer coupling, environment temperature overlap. highest conductivity at room achieved as more than 5 times of that single layer MoS2 when both layers heated 100% overlapped. Different mechanisms explained phonon density states, distribution, ITR. Our results not only could provide clues to master heat functional devices based heterojunctions, but also useful analyze other van der Waals nanosheets.
