Manganese influence on the semiconductive (Ba,Pb)TiO_3 ceramics

Zhi Yu Chen Ang(Mat. Sci-& Engineer. Dept. Phys. Dept. Zhejiang Univ. )Zhang Xuli Zhou Guoliang Wang Xiaozhen(Solid State Electr. Dept. Huazhong Univ. of Sci. & Tech. )  
The paper discussed the defect structure and the scmiconductivity in (Ba,Pb)TiO_3 PTC ceramics. The results show that the manganese acting as an acceptor had different influences on the complex defect and the semiconductivity in (Ba,Pb)TiO_3 ceramics under different sintering prccesses. A complex-defect model was adopted to explain the explain the experimental results well.
