摘要: A method has been developed for separation of ionic and electronic conductivity in mixed conductors. The procedure is accomplished by using blocking electrodes the Kramers–Kronig relations separating dc from total response. This was applied to lithium inserted deinserted sample Pr0.56Bi0.04Li0.2TiO3. material an conductor, after insertion, conduction appears sample. a similar electric behavior original material. does not need any previous model when processing data. Hence, it avoids those modeling related mistakes increases possibilities dielectric spectroscopy.
