Femtosecond dynamics in single wall carbon nanotube/poly(3-hexylthiophene) composites
(2008)Femtosecond transient absorption measurements on single wall carbon nanotube/poly(3-hexylthiophene) composites are used to investigate the relaxation dynamics of this blended material. The influence of the addition of ...

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 ...

Transient photoinduced absorption in ultrathin as-grown nanocrystalline silicon films
(2008)We have studied ultrafast carrier dynamics in nanocrystalline silicon films with thickness of a few nanometers where boundary-related states and quantum confinement play an important role. Transient non-degenerated ...
