Abstract
A one dimensional model for impurities in crystals is solved exactly. The results are compared with the effective mass theory. It turns out that this approximation is applicable even to deep states. For a more detailed calculation of these corrections are suggested. The theory is applied to impurities in Germanium and Silicon.
