Two-Path Phonon-Interference Resonance Induces a Stop Band in Silicon Crystal Matrix by Embedded Nanoparticles Array
Shiqian Hu, Lei Feng, Shao Cheng +2
In this work, we report a new stop-band formation mechanism by performing the atomistic Green's function calculation and the wave-packet molecular dynamics simulation for a system…

Probing the phonon surface interaction by wave packet simulation: effect of roughness and morphology
Cheng Shao, Qingyuan Rong, Ming Hu +1
One way to reduce the lattice thermal conductivity of solids is to induce additional phonon surface scattering through nanostructures. However, how phonons interact with boundaries…
