摘要：

A model is presented which explains recently reported temperature dependences of the density of state (DOS) distributions in amorphous materials. The model incorporates temporal fluctuations of the localized-state energies and predicts shallower DOS functions with local maxima and sharp edges for lower temperatures. These predictions are shown to be in good agreement with existing experimental data. Copyright (C) 1996 Elsevier Science Ltd
