Assignee: GWANGJU INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A memcapacitor comprising:
a first electrode that includes Nb-doped SrTiO3;
a dielectric thin film comprising SrMnO3 that is epitaxially grown on the first electrode, the dielectric thin film receiving a tensile force from the first electrode, such that the epitaxially grown dielectric thin film has an extended lattice constant as compared to an intrinsic lattice constant of SrMnO3; and
a second electrode disposed on the dielectric thin film,
wherein the dielectric thin film includes a passivation element that reduces a dielectric loss in SrMnO3 that is caused by the extended lattice constant, and
wherein the dielectric thin film has a variable dielectric constant caused by an externally-applied electric field.
