Abstract: In this work, the band offsets at the Ga0.5In0.5P/AlxGa0.5-xIn 0.5P 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, VBO, varies with x as VBO=0.433xeV, while the inferred conduction band offset CBO at Γ minimum (band-gap difference minus the valence band offset) varies in x as CBOΓ=0.787xeV. Our results are in good agreement with the experimental data. © 1998 American Institute of Physics.
