Abstract

This paper attempts to address the question of the role played by dimensionality in the observed optical transitions of porus silicon and related material systems. The effect of the degree of porosity on the transition energies, line widths and thermal stability. In addition more subtle effects observed in the thermal behaviour of the spectra which may relate to carrier trapping in a random potential of an imperfect localised system are reported. Comparisons with the spectral behaviour which would be predicted by quantum scale confinement of electronic particles are made.
