| Annotation | The paper presents an empirical model of the spectral dependence of the distribution of densities of electron states, which covers the main features of hydrogenated amorphous silicon. The effect of the degree of disorder the amorphous structure on the shape and size of tails in electronic states valence band and conduction band. These tails in the forbidden area affect many of the unique properties of amorphous semiconductors. The results can be applied for optimization of technology and modeling of many devices based on amorphous silicon (solar cells, transistors, etc.). |
