초록
In the present work, we report the synthesis, crystal structure, and charge transport properties of K doped BaSnO3(Ba0.8K0.2O3). The powder X-ray diffraction showed the formation of single phase with cubic structure. The total conductivity was measuredusing complex impedance analysis over a temperature range 30-750 oC and frequency 10 Hz to 10 MHz. The maximumconductivity was found to be 6.63 × 10-3 Scm-1 at 750 oC. The calculated activation energy from ac conductivity was foundto be 0.40 eV. The total conductivity was found to increase with increase in temperature.
