Claim 2:
3. A dielectric thin film, wherein
the dielectric thin film comprising a dielectric material that is epitaxially grown on an electrode, the dielectric thin film receiving a tensile force from the electrode, such that the epitaxially grown dielectric thin film has an extended lattice constant as compared with an intrinsic lattice constant of the dielectric material,
the dielectric thin film includes a passivation element that reduces a dielectric loss in the dielectric material that is caused by the extended lattice constant, and
the dielectric thin film has a variable dielectric constant due to an externally-applied electric field, the variable dielectric constant including at least three dielectric constants.
