摘要：

We use molecular-dynamics simulation of phonon wave-packets to study interfacial phonon scattering. Phonon scattering at a simple interface in a diamond-structured material is used to demonstrate the usefulness of the approach. We also present more recent results for interfacial scattering in a silicon nanowire. These preliminary results show that interfacial scattering in a nanoscale system is significantly different than scattering in the corresponding bulk system. Finally, we discuss methodological improvements in wave packet dynamics that will permit for direct comparison with experimental findings, including in the low-temperature regime where quantum effects are important.
