Abstract

The electrical Properties of ZnO added TiO$_2$were investigated by using the complex impedance measurement and voltage-current source and measurement unit. The electrical conductivity of ZnO added TiO$_2$decrease with increasing the content of ZnO. The frequency-dependent Ac conductivity increase as frequency increase. Also, the trend of capacitances is similar to the AC conductivity. The semicircles of impedance spectrum increase with increasing ZnO contents. The decrease of electrical conductivity seems to be the effect of ZnO acceptor adding.
