Abstract
A high energy density dielectric layer having relative dielectric permittivity greater than εR≥70 and thickness less than 1 micron that when formed between a primary electrode and the secondary electrode of a capacitor, wherein the high energy density dielectric has a dielectric polarization response that is determined solely by orbital deformations of the atomic species forming said high energy density dielectric.

A high energy density dielectric layer that polarizes and de-polarizes on femto-second (10−15 second) time scales comprising:
- a theoretically dense perovskite electroceramic further comprising a polycrystalline network of uniformly distributed grains having uniform grain size less than or equal to 50 nm, and,
- an intra-granular crystalline lattice that has an average atomic mass unit (amu) greater than or equal to 25 amu.
A method of forming a high energy density dielectric layer by incorporating into a theoretically dense perovskite electroceramic a polycrystalline network of uniformly distributed grains having uniform grain size equal to or less than or equal to 50 nm and an intra-granular crystalline lattice that has an average atomic mass (amu) greater than or equal to 25 nm.
