Calculation of the interband absorption spectra of amorphous semiconductors using the Kubo-Greenwood formula

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 read more 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 il barone wine states in amorphous semiconductors.
