COMMENT ON MONTE-CARLO SIMULATIONS OF THE RECOMBINATION DYNAMICS IN POROUS SILICON

The results of Monte Carlo simulations of the recombination dynamics i n porous silicon have been used to rule out explanations for porous si licon luminescence based on analogies with a-Si:H. In this comment we present arguments showing that the luminescence process of a-Si:H at l ow temperatures cannot be correctly described by the model system used in the calculations and the results obtained cannot rule out analogie s between porous silicon and a-Si:H.
