Article Preview

We study thermal properties of Z-shaped graphene nanojunctions (ZGNJs) with different corner deformation. It is found that the corner geometry of the Z-shaped junction has enormous influence on the thermal conductivity. The increase in angular width, the total phonon transmission gradually increased, when a maximum is reached, further increase in the angular width, total phonon transmission will be reduced because of the scattering of the corners and junctions. Our study provides a theoretical basis for the composite properties of crystal for the topology graphene.
