1. An apparatus comprising:
a capacitor structure having four layers, the four layers comprising:
a first electrode;
a second electrode;
a first ceramic material disposed between the first electrode and the second electrode; and
a second ceramic material disposed between the first ceramic material and at least one of the first electrode and the second electrode, the second ceramic material having a greater electrical conductivity than the first ceramic material and comprising a compound of the general formula La1-xSrxMnO3-δ wherein the electrical conductivity of La1-xSrxMnO3-δ changes from less than one sieman per centimeter to above 1000 siemans per centimeter at room temperature when x changes from 0 to 0.4.
