摘要

This study fabricates capacitors with two-layer structure and different compositions, 0.8Pb(Fe2/3W1/3)O3-0.2PbTiO 3-MnO and 0.7Pb(Fe2/3W1/3)O3-0. 3PbTiO3-MnO, by using the conventional solid state oxide reaction method. By using the temperature compensation effect and adjusting the thickness ratio of the two layers with different compositions, the temperature-dielectric peak is enhanced and smoothed. The dielectric loss, space charge polarization and dc conduction are suppressed at the highest temperature region. Furthermore, the Maxwell-Wagner model is used to fit and explain the dielectric behaviors. This study also provides suggestions and discussion related to the effect of the interfacial region based on the experimental data and fitting results.
