It is universally accepted that defects in materials scatter thermal phonons, and that this scattering is the reason why defects reduce the flow of heat relative to the defect-free material. However, ab-initio molecular-dynamics simulations which inc

Unexpectedly large isotope effects have been reported for the vibrational lifetimes of the H-C stretch mode of the CH2*defect in Si and the asymmetric stretch of interstitial O in Si as well. First-principles theory can explain these effects. The res
