Abstract

We present calculations showing the effect of placing impurities in quantum wells and heterostructure barriers. With a suitable configuration of the band edge, both the spacing of energy levels and their ordering can be controlled. The results should be of use in designing more flexible impurity infrared detectors and enhancing the radiative efficiency of transitions between impurity levels.
