Аннотация
A new method is presented for calculating the interband absorption spectrum for amorphous semiconductors using the Kubo-Greenwood formula in accordance with the Davis-Mott approximation method. It is shown that the calculated spectrum of interband absorption explained the experimental results, and a method is recommended to reduce the indefinite integral in the Kubo-Greenwood formula to a definite integral. It is explained that the boundaries of a definite integral are determined according to the empirical Tauc model, written for the distribution of the density of electronic states in amorphous semiconductors.
