Abstract
At any semiconductor heterojunction there is an interface dipole associated with quantum-mechanical tunneling, which depends on the band “lineup” between the two semiconductors. When the interface dipolar response dominates, the actual band discontinuity must be close to that unique value which would give a zero interface dipole. A simple criterion is proposed for this zero-dipole lineup, which gives excellent agreement with experimental band lineups. The close connection between heterojunction band lineups and Schottky barrier formation is emphasized.

These results for alloy heterojunc- tions, if extrapolated to the pure AlAs/GaAs interface, imply a valence-band discontinuity somewhat larger than given by the theory here, whereas the experimental value given in Table II, also based on extrapolation, is smaller than the theory.
