Abstract
We investigate the distribution of oscillator strengths for the recomb ination of excitons in a two-dimensional sample. trapped in local mini ma of the confinement potential: the results are derived from a statis tical topographic model of the potential. The predicted distribution o f oscillator strengths is very different from the Porter-Thomas distri bution which usually characterises disordered systems, and is notable for the fact that small oscillator strengths are extremely rare.
