Abstract

Methods of producing polycrystalline and single crystal dielectrics are disclosed, including dielectrics comprising CaCu3Ti4O12 or La3Ga5SiO4. Superior single crystals are manufactured with improved crystallinity by atomic lattice constant adjustments to the dielectric and to the substrate on which it is grown. Dielectric materials made according to the disclosed methods are useful for manufacture of energy storage devices, e.g. capacitors.
