摘要：

The optical properties (interband and intraband absorption) of a recently proposed structure-twinning superlattices-in diamond-type and zinc-blende-type semiconductors are calculated and discussed. The conduction-band intraband absorption is found to be rather weak, but the intraband absorption between the valence-band states has rather high values. Direct (phononless) interband absorption in twinning superlattices based on indirect gap semiconductors like germanium is also found to be allowed.
