Thermal transport properties in hybridised graphene and boron nitride ribbons (HGBNRs) under different strains are studied by using reverse nonequilibrium molecular dynamics simulations. It is found that the effect of strains on the thermal conductivity is different for different types of strains. When the tensile and shear strains are applied, the thermal conductivity can be modulated at least up to 50% at room temperature as the strain epsilon ranges from 0 to 0.2. However, when the compressive and flexural strains are respectively applied, the thermal conductivity is insensitive to the variation of the strain. In addition, it is also found that the thermal conductivity of HGBNRs depends sensitively on the dimension of the hybridised ribbon and the relative amount of h-BN to graphene. A brief analysis of these results is given.
