Local Pseudopotential Model for GaSb: Electronic and Optical Properties

Abstract
A local-pseudopotential calculation for GaSb using six form factors and one spin-orbit parameter has been found to give good agreement with the known features of the band structure. The reflectivity and wavelength-modulated reflectivity calculated using this band structure are in good agreement with experiment. All prominent features in the optical spectra can be identified with interband transitions in specific regions of the Brillouin zone.
