Strain effects on the interfacial thermal conductance of graphene/h-BN heterostructure

Previous experimental and computational results have confirmed that the thermal conductivity of a two-dimensional (2D) material can be considerably affected by strain. Numerous attention has been paid to explore relevant mechanisms. However, strain effects on interfacial conductance (ITC) 2D heterostructure attracted little attention. Herein, non-equilibrium molecular dynamics (NEMD) simulations were conducted graphene/hexagonal boron nitride (GR/h-BN) investigate ITC. Three types strains considered, i.e., tensile strain, compressive shear The indicate adjust ITC for GR/h-BN effectively, loading direction also influences Generally, reduces heterostructure, in addition BN-C system at small strain; both increase ITC, especially For NB-C system, it is more sensitive yx 0.06 most effective way strengthen Our show out-of-plane deformation weakens in-plane vibration atoms, leading reduction energy transport.
