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 ...
Femtosecond carrier dynamics in In 2O 3 nanocrystals
(2009)
We have studied carrier dynamics in In 2O 3 nanocrystals grown on a quartz substrate using chemical vapor deposition. Transient differential absorption measurements have been employed to investigate the relaxation dynamics ...
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 ...
Low temperature growth of In 2O 3 and InN nanocrystals on Si(111) via chemical vapour deposition based on the sublimation of NH 4Cl in In
(2009)
Indium oxide (In 2O 3) nanocrystals (NCs) have been obtained via atmospheric pressure, chemical vapour deposition (APCVD) on Si(111) via the direct oxidation of In with Ar:10% O 2 at 1000 °C but also at temperatures as low ...
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 ...
Structural properties of SnO2 nanowires and the effect of donor like defects on its charge distribution
(2013)
Tin oxide (SnO2) nanowires (NWs) with diameters of 50 nm, lengths up to 100 μm and a tetragonal rutile crystal structure have been grown by low pressure reactive vapour transport on 1 nm Au/Si(001). The free carrier density ...
