Field emission from randomly oriented ZnO nanowires

Chang, Yong-Qin; Chen, Xi-Hong; Zhang, Hong-Zhou; Qiang, Wen-Jiang; Long, Yi


Randomly oriented zinc oxide (ZnO)nanowires with different diameters were synthesized on a large scale on silicon substrates through a simple physical evaporation method. The nanowires exhibit stable and uniform electron field emission, and the turn-on field reduces with the diameter decreasing. The perfect field emission ability of the ZnOnanowires may be related to their rough surface and sharp curvature. Considering the efficient synthesis method and their excellent field emission...[Show more]
