Abstract

We present a self-consistent approach to describe ambipolar tunneling in asymmetrical double quantum wells under steady-state excitation and extend the results to the case of tunneling from a near-surface quantum well to surface states. The results of the model compare very well with the behavior observed in photoluminescence experiments in $I n G a A s / I n P$ asymmetric double quantum wells and in near-surface $A l G a A s / G a A s$ single quantum wells.
