Abstract
We report calcualtions which show that the heavy-hole valence band for cadmium zinc telluride multiple quantum wells (MQWs) has a highly distorted curvature close to the Brillouin zone centre due to the highly strained heterojunction interfaces. This curvature deformation decreases the heavy- hole effective mass which has exciting possibilities for ultrafast photonic circuits.
