Abstract

The sensitivity of the optical interband transition energies with respect to the band offsets is investigated theoretically for various potential profiles that can be simulated by thin layers of semiconductors. Guided by simple physical arguments we point out which potential profiles are favorable to reveal accurate values for the band offsets. A many-band envelope-function model is used to confirm our predictions quantitatively for GaAs/Ga1-xAlxAs multi-quantum-wells.
