Second‐harmonic generation from ZnO nanowires

physica status solidi c, 2008
AbstractOptical second‐harmonic generation (SHG) from ZnO nanowires is investigated in the region around the band gap. Strong multiphoton excited luminescence and SHG appearing together in the spectra from wires are separated and the SHG part is compared to that of a bulk crystal.

Magnetotransport in Co-Doped ZnO Nanowires

Nano Letters, 2009
Electrical and magnetotransport measurements were performed on individual Co-doped ZnO dilute magnetic semiconductor nanowires. The electron transport studies show that the electron mobility could be as high as 75 cm(2)/(V.s), and we observed positive magnetoresistivity (MR) at low magnetic field and negative MR at higher magnetic field.

Electrical properties of individual ZnO nanowires

Nanotechnology, 2009
The electrical properties of individual ZnO nanowires were investigated for two methods of fabricating nanowire-electrode junctions. The number of carriers in the nanowires was increased by electrostatically doping them by applying a gate voltage. The nanowires were chemically doped by introducing impurities during growth.

Electrical properties of ZnO single nanowires

Nanotechnology, 2015
We have investigated the electrical resistance R(T) of ZnO nanowires of ≈ 400 nm diameter as a function of temperature, between 30 K and 300 K, and frequency in the range 40 Hz to 30 MHz. The measurements were done on the as-prepared and after low-energy proton implantation at room temperature.

Nanowire Array Gratings with ZnO Combs

Nano Letters, 2005
Diffraction gratings are mainly manufactured by mechanical ruling, interference lithography, or resin replication, which generally require expensive equipment, complicated procedures, and a stable environment. We describe the controlled growth of self-organized microscale ZnO comb gratings by a simple one-step thermal evaporation and condensation ...

Aligned growth of ZnO nanowires and lasing in single ZnO nanowire optical cavities

Applied Physics B, 2008
Ordered ZnO nanowire arrays have been fabricated in N2 background gas by catalyst-free nanoparticle-assisted pulsed-laser deposition. A single ZnO nanowire was collected in an electrode gap by dielectrophoresis. Under the optical pumping above an exciting laser (λ= 355 nm) threshold of ∼ 334 kW/cm2, ultraviolet lasing action in a single ZnO nanowire ...

Growth of electrodeposited ZnO nanowires

2012 IEEE Sensors, 2012
Direct current electrodeposition method was used to deposit zinc oxide (ZnO) nanowire arrays from aqueous zinc chloride in ammonium chloride solution at 70° C onto 10 mm × 10 mm anodic alumina oxide (AAO) templates. The AAO templates featured an average pore diameter of 80 nm.
