The invention provides a dielectric-conductive substrate construct comprising a conductive material having a first surface and a second surface, and a dielectric film directly contacting the first surface and substantially covering the first surface, wherein the second surface is exposed to the ambient environment. Also provided is a method for producing a two component dielectric-conductive substrate, the method comprising supplying a base metal; and directly contacting a ceramic to the base metal to form a ceramic-metal interface while simultaneously preventing the formation of electrically insulative layers at the interface.
CONTRACTUAL ORIGIN OF THE INVENTION
 The U.S. Government has rights in this invention pursuant to Contract No. DE-AC02-06CH11357 between the U.S. Department of Energy and UChicago Argonne, LLC, representing Argonne National Laboratory.
