本文研制了n型半导化的施主掺杂PbTiO_3陶瓷,对其n型化机理进行了探讨,测量了不同温度下铅空位的扩散系数,文中还报道了n型化PbTiO_3陶瓷阻温双峰异常现象。
In this paper, a n-type semiconducting donor-doped PbTiO_3 ceramic was developed and its n-type mechanism was discussed. The diffusion coefficient of lead vacancies at different temperatures was measured. The bimodal anomalous temperature-dependent phenomenon of n-type PbTiO_3 ceramics was also reported.
