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 ... https://www.parisnaturalfoodes.shop/product-category/bio-regrow/
