Quantum well model and variation of the optical band gap in hydrogenated amorphous silicon carbon alloy films

Optical bandgap and quantum well model in hydrogenated amorphous silicon carbon alloy films

“…We have demonstrated, for the first time, that the models involving alloying or/and ordering breakdown while the model based on heterogeneity, is found to be the only model capable of explaining the observed variation of E opt with hydrogen, carbon composition and annealing temperature. The important results are summerized here while the details have been communicated elsewhere [26].…”
