In this work, the band offsets at the Ga0.5In0.5P/AlxGa0.5-xIn0.5P heterojunction lattice matched to (001) GaAs was calculated over the whole range of aluminum composition from x=0.0 to 0.5 using the first-principles pseudopotential method with virtual crystal approximation. The valence band offset,...
