Abstract
This invention relates to a method for improving the chemical and electrical performance characteristics of a high dielectric constant material. The method comprises the steps of first obtaining a barium containing high dielectric constant material, the material having an upper surface and then modifying the surface chemistry of said upper surface by interacting said upper surface with a gas reactant in a closed environment. In a variant of the method, the gas reactant preferentially reacting with upper surface as compared to the bulk.
