Abstract

The deactivation of nitrogen acceptors confined in quantum well structures by hydrogen (deuterium) have been investigated by optical spectroscopy. Hydrogen (deuterium) was incorporated into the samples by annealing them in an atmosphere of hydrogen and cadmium. The annealing temperature and annealing time were varied to determine the optimum condition at which the maximum passivation is achieved without causing structural degradation. The emissions related to nitrogen acceptors were monitored in low-temperature photoluminescence measurements in order to deduce the passivation effect. The results indicate that hydrogen can effectively neutralize the nitrogen acceptors in cadmium zinc telluride quantum well structures. It is estimated that as much as 90% of the nitrogen acceptors can be passivated by this method.
