Claim 23:
24. An integrated circuit device, comprising:
a capacitor comprising a ferroelectric oxide between first and second crystalline conductive oxide electrodes; and
the ferroelectric oxide having a perovskite crystal structure, wherein a lattice of the perovskite crystal structure comprises:
corner sites occupied by at least base corner elements comprising one or both of Ba and Bi, and
center sites interchangeably occupied by one or more base center elements and one or more dopant center elements, wherein the dopant center elements comprise one or more selected from the group consisting of Mn, Sc, Ti, V, Cr, Co, Ni, Cu and Zn,
wherein the ferroelectric oxide is epitaxially grown on the first crystalline conductive oxide electrode, such that at least a portion of the ferroelectric oxide is pseudomorphically formed on the first crystalline conductive oxide electrode.
