Abstract
We present calculations showing the effect of placing impurities in qu antum wells and heterostructure barriers. With a suitable configuratio n of the band edge, both the spacing of energy levels and their orderi ng can be controlled. The results should be of use in designing more f lexible impurity infrared detectors and enhancing the radiative effici ency of transitions between impurity levels.
