| Abstract |
Vertically aligned ZnO nanorods have been synthesized on a-plane sapphire via a metal
catalyzed vapor phase transport and condensation process in a two-zone vacuum furnace. Planar-tip
ZnO nanorods were synthesized using commercial ZnO and graphite powder as the source of Zn
vapor controlled by a simple vapor-liquid-solid (VLS) process. On the other hand, tapered-tip ZnO
nanorods were synthesized from pure ZnO powder governed by both VLS and vapor-solid processes.
From room temperature cathodoluminescence measurements, planar-tip ZnO nanorods are applicable
for room temperature UV nanolasers. |
