Abstract
We have investigated theoretically the optical properties of strained (001) ZnSe-(Zn, Cd)Se single quantum wells with a low cadmium content (similar to 10%). Due to the band offset and strain energy, the electr on-to-light-hole transitions are marginally type I. We compute the dis persion relations and joint density of states for a typical structure away from Gamma and show that the degeneracy call occur between lh(1) and hh(3) sub-bands in a large area of the Brillouin zone. This can ca ncel the selection rules for interband processes. (C) 1997 Elsevier Sc ience S.A.
