Abstract
The radiative decay rates of excitons localized by interface disorder in type-I indirect-gap quantum wells are explored as a function of the disorder-induced coherence area. In contrast to direct quantum wells, disorder is shown to enhance the radiative decay rate, and to provide the dominant radiative channel at low temperature.
