摘要:

AbstractThe angular force model is used to investigate phonon density of states of a‐Si0.5Ge0.5by considering only the first nearest neighbour interactions. A force constant decrease of the order of only 5% is observed when the phase changes from crystalline to amorphous system. The relevance of the obtained results to the Raman spectra is discusse
