摘要：
The Al-doped ZnO rod-like whiskers were synthesized by a simple hydrothermal method. The resistivity of Al-doped ZnO whisker (AZOw) samples significantly decreased with the increase of Al(3+) concentration, and showed a minimum when Al(3+) doping concentration was 2.0%. If Al(3+) concentration continued to increase, namely more than 2.0%, the resistivity of Al-doped ZnO samples would increase. So, in this study the optimum Al doping concentration was 2.0%, and the lowest electric resistivity (3.959 x 10(4) Omega cm) was obtained. (C) 2009 Elsevier B.V. All rights reserved.
