Limitations of a simplified dangling bond recombination model for a-Si:H

Li, Tsu-Tsung Andrew; McIntosh, Keith R.; Cuevas, Andres


The validity of a widely used simple closed-form expression for the recombination associated with dangling bonds in hydrogenated amorphous silicon (a-Si:H) is linked to the relative position of the distribution of the dangling bond states with respect to the quasi-Fermi levels for trapped electrons and holes. However, these quasi-Fermi levels for traps have not been derived before. In this work, we derive the four relevant quasi-Fermi levels for traps associated with dangling bonds in a-Si:H...[Show more]
