The valence band offset in GaSb-AlxGa1-xSb quantum wells has been determined by a light scattering method and found to be nearly the same as in their GaAs-AlxGa1-xAs counterparts. This result suggests the validity of a restricted form of the Common Anion Rule, which can be stated as follows: The valence band offset in a common anion heterostructure tends to be independent of the particular anion chosen. This new rule consistent with Tersoff's band lineup theory and also with a recent tight binding theory by Harrison and Tersoff.
