Abstract

Electrical Chracteristics of ZnO doped with Al$_2$O$_3$were investigated using complexe impedence measurements. The electrical conductivity of ZnO samples increased whithin 0.5mol% of Al$_2$O$_3$ doping, but decreased abode 0.5mol%. The increase and decrease of electrical conductivity seem to be the effect of Al$_2$O$_3$ doner doping and increasement of the number of grain boundary ZnO, respectively.
