Abstract

We compute the time-resolved and steady-state recombination spectra for excitons in disordered semiconductor strips on the basis of hopping theory. Exciton hopping undergoes a dimensional crossover when the hop length is comparable to the strip width. We show by Monte Carlo simulation that the analysis of time-resolved photoluminescence spectra for strips of differing widths provides a measurement of the parameters of the hopping theory and permits a determination of the hopping mechanism.
