摘要: Abstract We have combined measured 5K excitonic absorption peaks with calculations of the confined particle states to determine band offsets in GaAs(AlGa)As quantum well heterostructures. Our observations are best fitted a conduction band-valence split about 75:25. This contrasts currently accepted value 85:15 and recently proposed 60:40.
