Abstract
The physics governing deep levels in superlattices and quantum wells is elucidated, with emphasis on the importance of shallow-deep transitions caused by a band edge passing through a deep level, and the accompanying change in doping character of the impurity.

This limit on the band gap of the superlattice may not be obvious in Kronig-Penney models, in which the conduction band edge of the superlattice is the first confined quantum well state.
