Abstract:

In summary, we demonstrate the ZnO nanotetrapod synthesized by a simple vapor phase transport process can be good field emission emitters. The field emission measurement as-synthesized materials reveal that these samples have low turn-on field and threshold field. The technique in this work opens the door for quite simple and easy fabrication with low cost. The one-dimensional ZnO nanostructures could possess a potential application in FED and other optoelectronic devices.
