Consider the GaAs/AlxGa1-xAs (0 ≤ x < 1). Assume that the band discontinuity distribution between the conduction and valence band is given by ΔEc = 0.6ΔEg (direct) ΔEv = 0.4ΔEg (direct) where ΔEg (direct) is the bandgap discontinuity between AlGaAs (even if the material is indirect) and GaAs. Calculate the valence and conduction band offsets as a function of Al composition.
