The amorphous silicon (a-Si) is a material which has had a great acceptance in the microelectronic industry field due to its low cost in comparison with the one of crystalline silicon (c-Si).This material has a random network in its atomic structure, since its atoms are not located to either a specific angles or distance.In 1969, Chittik et al. [1] added hydrogen to the amorphous silicon finding a beneficial effect, Paper No.
