چکیده
Zinc oxide (ZnO) is one of the light in ultraviolet (UV) region. In addition, ZnO nano attracting increasing research interest as buildin optoelectronic applications. We have succeede vertically-aligned ZnO nanostructures by laser inter which is catalyst-free and non-contact techniq vertically-aligned ZnO nanowall arrays were two-beam interference. The maximum height and a the ZnO nanowalls were about 4.5 μm and 200 nm lasing from a piece of the ZnO nanowall was obtai harmonic of a Q-switched Nd:YAG laser excitation threshold power density for lasing was abo Furthermore, UV lasing from the vertically-aligned also achieved. The results indicate that ZnO nanow to random laser. Keywords—Zinc Oxide, nanowall, interferenc

Fabrication and Optimization of Vertically Aligned ZnO Nanorod Array-Based UV Photodetectors via Selective Hydrothermal Synthesis
Vertically aligned ZnO nanorod array (NRA)-based ultraviolet (UV) photodetectors (PDs) were successfully fabricated and optimized via a facile hydrothermal process. Using a shadow mask technique, the thin ZnO seed layer was deposited between the patterned Au/Ti electrodes to bridge the electrodes. Thus, both the Au electrodes could be connected by the ZnO seed layer. As the sample was immersed ...

ZnO was grown on sapphire substrate by metal-organic chemical vapor deposition using the diethylzinc (DEZn) and oxygen (O(2)) as source chemicals at 500 degrees C. Influences of the chamber pressure and O(2)/DEZn ratio on the ZnO structural properties were discussed. It was found that the chamber pressure has significant effects on the morphology of ZnO and could result in various structures of...
