OPTICAL-TRANSITIONS IN SI GE SUPERLATTICES

We have performed self-consistent field calculations of the electronic structure of Si/Ge square-well superlattices within the effective-mas s theory. We have computed the optical transition matrix elements invo lving transitions from the hole states to states in the conduction ban d, and we have also computed the oscillator strength matrix elements f or the transitions between the states in the conduction band.
