Semiempirical molecular orbital calculations were carried out in order to estimate static charge fluctuation in a-Si:H. We derived an empirical formula determing Si-Si bond lengths as a function of atomic net charges. It was found that Si-Si bonds adjacent to Si-H bonds are longer, i.e. weaker, than others.
