Electroluminescence from annealed ZnO nanowires
2006 Sixth IEEE Conference on Nanotechnology, 2006We report the effect of thermal annealing on the room-temperature electroluminescence in vertically oriented ZnO nanowires. Ultra-violet luminescence around 390 nm and a broad defect-related band centered at 620 nm are observed. The ZnO nanowires are grown in electrodeposition on SnO 2 -coated glass substrates, employing a technique that is suitable ...

Diffusion thermopower in ZnO nanowires
AIP Conference Proceedings, 2014Low temperature acoustic phonon limited diffusion thermopower (Sd) in wurtzite ZnO nanowires is studied considering inelasticity of the scattering. An expression for scattering rate due to piezoelectric (PZ) acoustic phonon coupling is given. Sd calculated in elastic approximation, used in literature, is found to overestimate.

Nanoindentation of vertical ZnO nanowires
Physica E: Low-dimensional Systems and Nanostructures, 2007We report the experimental observations of buckling instabilities of vertical well-aligned single-crystal ZnO nanowires prepared on ZnO:Ga/glass templates. It was found that critical buckling load and buckling energy of the ZnO nanowires were 215mN and 3.69 10 11 J, respectively.

Pt ∕ ZnO nanowire Schottky diodes
Applied Physics Letters, 2004Pt Schottky diodes were formed on single ZnO nanowires grown by site-selective molecular-beam epitaxy and then transferred to SiO2-coated Si substrates. The diodes exhibit excellent ideality factors of 1.1 at 25 °C and very low (1.5×10−10A, equivalent to 2.35Acm−2, at −10V) reverse currents.

Nonlinear optics with ZnO nanowires
physica status solidi (b), 2009AbstractSecond‐harmonic generation and two‐photon induced photoluminescence from arrays of ZnO nanowires and single nanowires under excitation with femtosecond pulses is experimentally studied. The ratio of relevant components of the nonlinear χ(2) tensor is obtained.

ZnO Nanowires Synthesis and Characterization
ECS Meeting Abstracts, 2016In this study, a two-zone furnace had been used to grow ZnO nanowires (NWs) on Si (100) substrates by thermal evaporation method via the vapor-solid (VS) mechanism. We mixed zinc oxide powder and graphite powder as source. By controlling the growth temperature, source temperature, growth pressure, source amount, growth time, growth position and carrier
