Temperature Dependence of the Main Parameters Determining the Interband Absorption Spectrum of a Si:H
Abstract
In this work, the temperature dependence of the interband optical absorption coefficient of hydrogenated amorphous silicon (а-Si:H) has been investigated both experimentally and theoretically. By fitting the values obtained from the optical absorption coefficient formula, the temperature dependence of the characteristic vibration energy of а-Si:H was studied using the Bose-Einstein and Varshni formulas.
