Thermal oxidation and facet-formation mechanisms of Si nanowires
(2014)
Silicon nanowires were grown along the [111] direction on Si(001) by the vapor-liquid-solid mechanism using 1 nm Au as a catalyst. They were subsequently oxidized at 900 °C for 60 min, 120 min and 180 min, which lead to ...
Ultrafast carrier relaxation in inn nanowires grown by reactive vapor transport
(2009)
We have studied femtosecond carrier dynamics in InN nanowires grown by reactive vapor transport. Transient differential absorption measurements have been employed to investigate the relaxation dynamics of photogenerated ...
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 ...
Synthesis of hybrid polymethacrylate-noble metal (M = Au, Pd) nanoparticles for the growth of metal-oxide semiconductor nanowires
(2012)
Metal-oxide semiconductor nanowires (NWs) such as ZnO, β-Ga 2O 3 and SnO 2 with diameters of tens of nanometres and lengths of many micrometres have been grown using micellar nanohybrids consisting of methacrylate-based ...
A systematic study of the nitridation of SnO 2 nanowires grown by the vapor liquid solid mechanism
(2012)
SnO 2 nanowires (NWs) with diameters of 50 nm and lengths ≥10 μm have been grown at 800 °C on 1.0 nm Au/Si(001) via the vapor liquid solid mechanism and the low pressure chemical vapor deposition. These exhibited clear ...
Synthesis of Tin nitride Sn xN y nanowires by chemical vapour deposition
(2009)
Tin nitride (Sn xN y) nanowires have been grown for the first time by chemical vapour deposition on n-type Si(111) and in particular by nitridation of Sn containing NH 4Cl at 450 °C under a steady flow of NH 3. The Sn xN ...
High yield-low temperature growth of indium sulphide nanowires via chemical vapor deposition
(2010)
Indium sulphide nanowires (NWs) have been grown on Si via the reaction of In and InCl3 with H2S using chemical vapor deposition at temperatures as low as 250 °C. We find that the growth of InxSy NWs via the direct reaction ...
Enhanced growth and photoluminescence properties of SnxN y (x>y) nanowires grown by halide chemical vapor deposition
(2011)
Tin nitride nanowires have been grown by halide chemical vapor deposition via the reaction of Sn with NH4Cl at 425 °C under a steady flow of NH3 using small ramp rates y) with a hexagonal structure, i.e. c=5.193 , a=3.725 ...
Hydride-assisted growth of GaN nanowires on Au/Si(0 0 1) via the reaction of Ga with NH3 and H2
(2010)
High quality, straight GaN nanowires (NWs) with diameters of 50 nm and lengths up to 3 μm have been grown on Si(0 0 1) using Au as a catalyst and the direct reaction of Ga with NH3 and N2:H2 at 900 °C. These exhibited ...
