Abstract

Silicon nanocrystals embedded in a lattice-matched Gd2 O 3 matrix exhibit large size-dependent bandgap widening. Measurements of photocharging spectra of these crystals indicate only a marginal variation in the photoionization threshold energy. The latter suggests that most of the confinement-induced bandgap width variation is caused by the upward shift of the Si nanocrystal conduction band bottom.
