Abstract

A method of producing multilayered conformal coatings of tunable, low electronic loss ceramic composites is carried out by mixing two-phase BSTO/MgO into a base solution of typical lab grade acetone to form a mixed solution, inserting two platinum sheets separated into the mixed solution, applying a constant direct current (DC) bias across the two platinum sheets acting as electrodes, and stirring to reduce sedimentation of particles using a magnetic stirrer. Deposition is also performed on insulating substrates by initially coating them with conducting films of Au, performing BSTO deposition, and subsequently sintering the dielectric film so that the underlying metal film evaporates.
