| 英文摘要 | The defect and electrical conduction in Mn-doped CaCu3-xMnxTi4O12 (0 <= x <= 1) negative temperature coefficient (NTC) ceramics were successfully investigated by using defect chemistry theory in combination with X-ray photoelectron spectroscopy (XPS) analysis. An approximate linear relationship between the natural logarithm of the resistivity and the reciprocal temperature for Mn-doped samples was observed in comparison to CaCu3Ti4O12, and these linear electrical behaviors were extremely enhanced with increasing Mn content. As the Mn concentration increased, Ea(25-500 degrees C) decreased and Ea(500-800 degrees C) increased at first and then slightly decreased. The defect in these ceramics may mainly result from the cation non-stoichiometry in the temperature range from ambient to 500 degrees C and oxygen vacancy after 500 degrees C. |
