摘要：

Vertically well-aligned ZnO nanocolumns were grown on Al2O3 (0 0 0 1) substrates via metalorganic chemical vapor deposition without using any metal catalyst. Their morphology was investigated as a function of the growth temperature (T-g), which was found to be a key processing parameter to control their shape. At T-g >= 450 degrees C, vertically well-aligned ZnO nanocolumns started to grow. It was found that a higher T-g yielded slimmer, needle shaped nanocolumns, whereas a lower T-g yielded thicker nanocolumns. (c) 2005 Elsevier B.V. All rights reserved.
