Carrier dynamics in Β-Ga2O3 nanowires

Othonos, A.; Zervos, Matthew; Christofides, C. (2010)

Carrier dynamics have been investigated in Β-Ga2O 3 nanowires (NWs) grown by the vapor-liquid-solid mechanism, using ultrashort transient absorption spectroscopy in conjunction with time-correlating single photon counting ...

Carrier relaxation dynamics in SnxNy nanowires grown by chemical vapor deposition

Othonos, A.; Zervos, Matthew (2009)

Carrier relaxation dynamics in tin nitride (SnxNy) nanowires have been investigated using femtosecond transient absorption spectroscopy. The nanowires were grown directly on quartz using chemical vapor deposition and had ...

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 ...

Ultrafast hole carrier relaxation dynamics in p-type CuO nanowires

Othonos, A.; Zervos, Matthew (2011)

Ultrafast hole carrier relaxation dynamics in CuO nanowires have been investigated using transient absorption spectroscopy. Following femtosecond pulse excitation in a non-collinear pump-probe configuration, a combination ...
