1433 Si-Ge 超格子における熱伝導分子動力学シミュレーション  [in Japanese] Thermal conducting molecular, kinetic simulation in Si-Ge super-lattice  [in Japanese]

Heat conduction in mechanism nano structure were studied by using molecular dynamics (MD) simulations. Motions of 1,728 atoms were simulated at constant temperature with periodic boundary conditions. To calculate the temperature distribution and the thermal conductivity, we simulate the lattice vibration of Si-Ge super-lattics The thermal conductivity has decreased greatly by 001 perpendicular to the interface of Si-Ge.
