Abstract

The optical absorption coefficient for direct allowed interband transitions between states L⁺₆ and L⁻₆ is calculated within the framework of a multiband model, including six bands in a k · p treatment. Due to the enhanced joint density of states at higher energies in the multiband model as compared with the Dimmock‐model a good agreement is obtained between calculated and experimental absorption spectrum also at photon energies hw > 2E_G.
