Fig. 3: The left panel shows the temperature dependence of thermal conductivity K for a pristine monolayer of MoS2 from MD simulations (orange).

Also shown are the quantum-corrected values (blue) obtained by multiplying κ with the specific heat which includes quantum corrections9. Evidently, the quantum contribution to thermal conductivity is much larger at lower temperatures. The right panel shows thermal conductivity in MoS2 sheets as a function of number of voids. Thermal conductivity drops by an order of magnitude due to the presence of a single void. The number of voids does not make a difference thereafter.
