M. Wilkinson et al., DISTRIBUTION OF OSCILLATOR-STRENGTHS FOR RECOMBINATION OF LOCALIZED EXCITONS IN 2 DIMENSIONS, Chaos, solitons and fractals, 8(7-8), 1997, pp. 1169-1177
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. (C) 1
