Anharmonic Decay of Vibrational States in Amorphous Silicon
arXiv:cond-mat/9605101 · doi:10.1103/PhysRevLett.77.3839
Abstract
Anharmonic decay rates are calculated for a realistic atomic model of amorphous silicon. The results show that the vibrational states decay on picosecond timescales and follow the two-mode density of states, similar to crystalline silicon, but somewhat faster. Surprisingly little change occurs for localized states. These results disagree with a recent experiment.
