摘要:

A prominent Urbach tail is introduced in the absorption spectra of In0.72Ga0.28As0.60P0.40, by Ge doping, due to transitions from disorder‐induced localized states at the valence‐band edge to conduction band. Different components of the disorder have been considered. A model calculation, considering multiphonon emission, has been made.
