Research output: Contribution to journalArticlepeer-review


A novel analytic approach for calculating superlattice effective masses both perpendicular and parallel to the layer planes is summarized. The approach is based on the crystalline oscillator strength ("f-") sum rule and the envelope function approximation. Applications to GaAs Ga1-xAlxAs and HgTe CdTe yield excellent agreement with experiment for a conduction : valence band offset ratio of 70:30 and a valence band offset near zero, respectively.
