Abstract

In this work we examine the suppression of phonon transport in another example, Si and SiPt heterostructures (3D). This heterostrucure is believed to have the benefit that the electrical conductance can be kept high while the phonon propagation is suppressed due to the large acoustic impedance mismatch between Si and PtSi.
