In this research, we analyze the conductivity properties of ZnO nanorods was grown by using a hydrothermal method. We use the I-V characteristics test to determine the conductivity properties. We apply voltage in the range of 1–30 volt. The result from the I-V characteristics shows that the greater value of the applied voltage produces a decrease of the resistance value. The resistance value obtained at a given voltage of 1 volt is 7.8 kOhm, while at a voltages of 30 volts is 0.5 kOhm. The I-V curve profile indicates that interface between ZnO nanorods and Au-electrode shows a Schottky barrier characteristics.
