An Analysis of the Variation in Calculated Confined-State Energies Using Different Envelope-Function Models

Authors: Beşire GÖNÜL

Abstract: We investigate different formulations of the envelope-function method and show that the accuracy of the calculated zone-centre confinement energies can be calculated by means of bulk band structure. We show how coupling to the conduction and spin-split-off bands can decrease the light-hole zone-centre confinement energies and lead to significant differences in the calculated subband dispersion.
