The thermal conductivities of AlxGa1-xN and In xGa1-xN mixed crystal and AlN/GaN superlattices were investigated by molecular dynamics simulation. We used Stillinger-Weber potentials, and Green-Kubo's formula was employed to calculate thermal conductivity. The results showed that the value of thermal conductivity of Al.0.5Ga0.5N was about 1/20 smaller than that of GaN. It was also found that the thermal conductivity of AlN/GaN superlattices along the c-axis, which is parallel to the growth direction, was much less than that of bulk GaN.
