Defect states of chemical vapor deposition grown GaN nanowires: Effects and mechanisms in the relaxation of carriers

Tsokkou, D.; Othonos, A.; Zervos, Matthew (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 ...

Femtosecond carrier dynamics in In 2O 3 nanocrystals

Othonos, A.; Zervos, Matthew; Tsokkou, D. (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

Othonos, A.; Zervos, Matthew; Tsokkou, D. (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 ...
