Abstract
A simple theoretical model is proposed to explain the recently observed valence-band structure of CdSn and similar chalcopyrite crystals. The valence bands of a chalcopyrite crystal are regarded as equivalent to those of a strained version of its binary analog. This model predicts the signs and magnitudes of the valence-band splittings observed in CdSn and ZnSi. We show further that the quasicubic model explains quantitatively the unusual polarization dependences previously reported.
