Carrier dynamics in InS nanowires grown via chemical vapor deposition

Othonos, A.; Zervos, Matthew (2010)

Transient femtosecond absorption spectroscopy and timecorrelating single photon counting (TCSPC) photoluminescence (PL) were employed to study InS nanowires (NWs) grown by chemical vapor deposition (CVD) and determine the ...

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 ...
