The strong effect of an electric field on the ionization energy of deep acceptors in asymmetric quantum-well systems is due to the field-dependence of the mixing of the states in the heavyand light-hole subbands. The dependence of the ionization energy on the field and the position of impurities in the structure was calculated in the strongly localized potential model. © 1995 American Institute of Physics.
