Carrier dynamics and conductivity of SnO 2 nanowires investigated by time-resolved terahertz spectroscopy
(2012)
THz spectroscopy has been applied to investigate the photo-induced and intrinsic conductivity in SnO 2 nanowires using the Drude-Smith model. The refractive index of the nanowires was found to decrease from 2.4 to 2.1 with ...
Ultrafast time-resolved spectroscopy of In2 O3 nanowires
(2009)
Ultrafast carrier dynamics in In2 O3 nanowires with an average diameter of ≈100±20 nm grown by the vapor-liquid-solid method have been investigated in detail using differential absorption spectroscopy with femtosecond ...
Tin oxide nanowires: The influence of trap states on ultrafast carrier relaxation
(2009)
We have studied the optical properties and carrier dynamics in SnO 2 nanowires (NWs) with an average radius of 50 nm that were grown via the vapor-liquid solid method. Transient differential absorption measurements have ...
Defect states of chemical vapor deposition grown GaN nanowires: Effects and mechanisms in the relaxation of carriers
(2009)
Carrier relaxation in GaN nanowires, grown by atmospheric pressure chemical vapor deposition, via direct nitridation of Ga with NH3 at 950 °C has been investigated in detail. Differential absorption measurements reveal a ...
