First-Principles Analysis of Vibrational Properties of Type II SiGe Alloy Clathrates

We have mostly performed vibrational studies of Type-II silicon-germanium clathrate alloys, namely, Si<sub>136-x</sub>Ge<sub>x</sub> (0 &lt; <i>x</i> &#8804; 128), using periodic density functional theory (DFT). Our computed lattice constant for various st...
