| Summary: | 碩士 === 國立成功大學 === 材料科學及工程學系碩博士班 === 98 === CaCu3Ti4O12(CCTO) is a dielectric material which has pervoskite structure. This material has ultrahigh dielectric constant (about 104~105) at room temperature, and it is independent of temperature. The mechanism for inducing large dielectric response of CaCu3Ti4O12 still remains unresolved. Presently, grain boundary and domain boundary are thought as the origin of such ultrahigh dielectric constant.
In this research, we analyze the dielectric behavior of MST- doped CaCu3Ti4O12 and the existence of electrode-contact effect.
