Abstract

In an embodiment, a dielectric structure comprising solid dielectric regions incorporating a plurality of regions of vacuum or gas. In certain embodiments, the dielectric constant of the regions of solid dielectrics have a dielectric constant greater than 4. In certain embodiments, each of the plurality of regions of vacuum or gas or the regions of solid dielectrics is anisotropic with an aspect ratio of at least four. In certain embodiments, the smallest average dimension of a plurality of regions of vacuum or gas and/or solid dielectrics have a length of less than 1 micron. In certain embodiments, the dielectric structure has a higher electrical energy density in the regions of vacuum or gas than in the solid matrix. In certain embodiments, one or more electrodes of the capacitive structure are coated with a solid insulating layer without an interface between a region of vacuum or gas and electrode.

Dependent claims

An article, comprising:

a dielectric structure comprising:
one or more regions of at least one solid material having a dielectric constant greater than four, wherein at least one region of the one or more regions of at least one solid material has a first average particle dimension (dmaj) and a second average particle dimension (dmin);
and
a plurality of regions of vacuum or gas, wherein at least one region of vacuum or gas of the plurality of regions of vacuum or gas has a first average particle dimension (d′maj) and a second average particle dimension (d′min);
wherein at least one of:
an aspect ratio of dmaj to dmin for the at least one region of at least one solid material is equal to or greater than four;
and
an aspect ratio of d′maj to d′min for the at least one region of vacuum or gas is equal to or greater than four, and
wherein the plurality of regions of vacuum or gas are dispersed throughout the one or more regions of at least one solid material such that, upon application of an electric field to the dielectric structure, the average electric field in the one or more regions of at least one solid material is less than the average electric field in the plurality of regions of vacuum or gas.
