Abstract
The Electrical properties as a function of temperature were investigated at elevated temperatures (300 K - 800 K) on quenched samples of donor doped La-BaTiO<sub>3</sub> system. The resistivity and carrier concentration increased with increasing temperature. The mobility of the sample shows exponential temperature dependence and the value of mobility is in well agreement with the theoretical values. From the conductivity data the activation energy was calculated (0.036 eV) and revealed that the conduction mechanism in this system is thermally activated.
