The synthesis of nanocomposite thin films (NCTFs) by atomization of a colloidal solution in atmospheric-pressure discharges (APDs) has revealed a great potential. In this work, Scanning Electron Microscopy (SEM) is used to analyze the relationship between the voltage excitation waveform in a plane-to-plane Townsend dielectric barrier discharge and ...
Crack-free GaN epitaxial layer was obtained through inserting 80 nm graded AlGaN buffer layer between GaN epilayer and high temperature AlN buffer on 2-in Si(111) substrates by metal organic chemical vapor deposition. This paper investigated the influence of AlGaN buffer thickness on the structural properties of the GaN epilayer. It was confirmed f...
We investigate the omnidirectional absorption enhancement induced by the excitation of the localized surface plasmon in the hybrid system consisting of a gold nanowire array embedded in a slab waveguide. Assisted by the waveguide layer, the hybrid system can support the localized waveguide-plasmon resonances for a wide range of incident angles. The...
The valence-band offset of the wurtzite ZnO/rutile TiO(2) heterojunction was directly determined by x-ray photoelectron spectroscopy. The wurtzite ZnO (0001) layer was grown on commercial rutile (101) TiO(2) by metal-organic chemical-vapor deposition. The results show that the valence-band offset is 0.14 +/- 0.05 eV, which agrees well with previous...
We observe obviously different diffraction efficiencies with forward and reverse dc voltages in a forced-light-scattering (FLS) experiment for a cell with ZnO nanorod doped in only one poly (vinyl alcohol) (PVA) layer. When a dc voltage with a positive pole on the ZnO nanorod doped side is applied, the excited charge carriers primarily move along t...
