| Abstract: Micron-scale trumpet tubular ZnO crystals were synthesized by Chemical Vapor Transport (CVT) process. After the ZnO powder was deoxidized in the stove by H2 from NH3 decomposition at high temperature, the zinc vapor was transported by Ar to the high-temperature crystal growth region. The zinc vapor reacted with O2 in the crystal growth region, and ZnO crystals were obtained. The length of the crystals was about hundreds micron and the diameter was about tens micron. The strong polar growth tendency and the self-organized characteristics were found in ZnO crystals growing process. |
