Thermal Conductivities of Suspended Graphene/MoS 2 Van der Waals Heterostructures Measured by Raman Spectroscopy

) of monolayer graphene prepared by chemical vapor deposition. This work not only demonstrates the measurement of in-plane thermal conductivities of van der Waals heterostructures of 2D materials but also shows the great potential of using monolayer graphene to significantly enhance heat dissipation in ultrathin materials.
