Enhancing phonon transmission across a Si/Ge interface by atomic roughness: First-principles study with the Green's function method
Knowledge on phonon transmittance as a function of phonon frequency and incidence angle at interfaces is vital for multiscale modeling of heat transport in nanostructured materials. Although thermal conductivity reduction in nanostructured materials can usually be described by phonon scattering due...
