Abstract
A direct experimental test has revealed that heterojunction energy-band discontinuities are nontransitive. This result was obtained by an x-ray photoemission-spectroscopy investigation of abrupt (110) interfaces in the heterojunction series Ge/CuBr, CuBr/GaAs, and GaAs/Ge. The sum of the valence-band discontinuities for these intefaces is 0.64 ± 0.05 eV, a large deviation from the zero sum expected by transitivity.
