Abstract

In this paper, the performance parameters, capacitance and leakage current of Al2O3, ZnO and MgO doped Ba0.7Sr0.3TiO3 ceramics based metal-insulator-metal (MIM) capacitors are investigated. The specific capacitance of intrinsic Ba0.7Sr0.3TiO3 ceramic based MIM capacitor changes with frequency whereas Al2O3 doped Ba0.7Sr0.3TiO3 ceramics based MIM capacitor exhibits almost frequency independent specific capacitance. 2.0 wt% ZnO doped Ba0.7Sr0.3TiO3 ceramics based MIM capacitor exhibits highest specific capacitance. The doping of Ba0.7Sr0.3TiO3 ceramics with ZnO is not sufficient for enhancing leakage current performance. On investigation, 4.0 wt% MgO doped Ba0.7Sr0.3TiO3 ceramics based MIM capacitor is found better for energy storage application.

Al2O3,ZnO和MgO掺杂Ba0.7Sr0.3TiO3陶瓷基MIM电容器的电学性能研究

摘要

本文研究了Al 2 O 3,ZnO和MgO掺杂的Ba 0.7 Sr 0.3 TiO 3陶瓷基金属-绝缘体-金属(MIM)电容器的性能参数,电容和漏电流。本征Ba 0.7 Sr 0.3 TiO 3陶瓷基MIM电容器的比电容随频率变化,而掺杂Al 2 O 3的Ba 0.7 Sr 0.3 TiO 3陶瓷基MIM电容器的比电容几乎与频率无关。2.0 wt%ZnO掺杂的Ba 0.7 Sr 0.3 TiO3陶瓷基MIM电容器具有最高的比电容。ZnO掺杂Ba 0.7 Sr 0.3 TiO 3陶瓷不足以增强漏电流性能。经研究,发现4.0%(重量)的MgO掺杂的Ba 0.7 Sr 0.3 TiO 3陶瓷基MIM电容器更适合储能应用。
