Molecular dynamics study of structural and dynamical properties of amorphous Si-Ge alloys

摘要: Structural and dynamical properties of amorphous silicon-germanium (a-Si 1 - x Ge ) alloys have been examined by molecular dynamics simulations using the Tersoff interatomic potential. Amorphous networks were generated byrapid quenching from liquid Si alloys. Good agreement was obtained between simulated experimentally measured radial distribution functions phonon densities states, suggesting that potential is useful for analyzing atomic configurations vibrational a-Si Local atomistic structures, such as topological chemical short-range order also in detail, we compared them with experimental theoretical results reported previously. On basis here, proposed bond length angle around atoms more distortion than those networks.
