High permittivity nanocomposites for electronic devices

An electronic device comprising a nanocomposite of carbon nanodomains homogeneously embedded in an insulating ceramic matrix, wherein the size and distribution of carbon nanodomains is such that the nanocomposite has a permittivity of greater than or equal to 200, wherein the carbon nanodomains have dimensions of less than about 20 nm, wherein the carbon nanodomains constitute between from about 5 vol % to about 40 vol % of the nanocomposite, and wherein the carbon nanodomains are thermally formed in situ via pyrolysis at a temperature of from about 800° C. to about 1200° C. during formation of the insulating ceramic matrix.

An electronic device comprising a nanocomposite of carbon nanodomains homogeneously embedded in an insulating ceramic matrix, wherein the size and distribution of carbon nanodomains is such that the nanocomposite has a permittivity of greater than or equal to 200, and wherein the nanocomposite is a component in a dielectric material, wherein the dielectric material is a film.
