Determination of critical points on silicon nanofilms: Surface and quantum confinement effects
(2008)In this work, we present a comprehensive study of the optical properties of nanocrystalline silicon films with thickness varied from 5 to 30 nm. Spectroscopic ellipsometry is employed to determine the dielectric functions ...

Surface-related states in oxidized silicon nanocrystals enhance carrier relaxation and inhibit auger recombination
(2008)We have studied ultrafast carrier dynamics in oxidized silicon nanocrystals (NCs) and the role that surface-related states play in the various relaxation mechanisms over a broad range of photon excitation energy corresponding ...
