Query: MoS2-graphene in-plane contact for high interfacial thermal conduction   Recent studies showed that the in-plane and inter-plane thermal
conductivities of two-dimensional (2D) MoS2 are low, posing a significant
challenge in heat management in MoS2-based electronic devices. To address this
challenge, we design the interfaces between MoS2 and graphene by fully
utilizing graphene, a 2D material with an ultra-high thermal conduction. We
first perform ab initio atomistic simulations to understand the bonding nature
and structure stability of the interfaces. Our results show that the designed
interfaces, which are found to be connected together by strong covalent bonds
between Mo and C atoms, are energetically stable. We then perform molecular
dynamics simulations to investigate the interfacial thermal conductance. It is
found surprisingly that the interface thermal conductance is high, comparable
to that of graphene-metal covalent-bonded interfaces. Importantly, each
interfacial Mo-C bond serves as an independent thermal channel, enabling the
modulation of interfacial thermal conductance by controlling Mo vacancy
concentration at the interface. The present work provides a viable route for
heat management in MoS2 based electronic devices.
