Band-tail photoluminescence in nanocrystalline Si

The characteristic subgap photoluminescence (PL) observed in nanocrystalline Si films was found to shift to higher energies with increasing optical gap and decreasing crystallite size. This behavior, along with the temperature dependence of the PL, is consistent with transitions between band-tail st...
