Abstract
The un-doped nanocrystalline BaTiO3 (BT) ceramics samples with different grain size were prepared and its electrical properties were measured. It was found that the conductivity of samples decreases with increasing temperature at some high frequency. The activation energy of carriers is calculated experimentally and theoretically for different samples. The results show that the accumulation of charges at grain boundary is the chief factor at high frequency, which lead to the decrease of conductivity with increasing temperature.
