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 ...
