Metal-free monolithic epitaxial graphene-on-diamond PWB
According to some embodiments, an apparatus includes a circuit board made of polycrystalline diamond. The circuit board is formed by deposition of layers of poly(hydridocarbyne). Each layer has the geometry of a cross section of the circuit board. The circuit board is further formed by pyrolysis of the layers of poly(hydridocarbyne) at a temperature greater than or equal to 100 degrees Celsius and less than or equal to 800 degrees Celsius. The apparatus additionally includes a plurality of tubes formed within the circuit board. The tubes have a plurality of terminations at one or more surfaces of the circuit board. Each tube comprises a layer of graphene that is operable to permit each tube to conduct electrical current. Each layer of graphene is formed by thermolysis of the polycrystalline diamond circuit board at a temperature greater than or equal to 900 degrees Celsius. Each tube is substantially hollow each layer of graphene forms an outer surface of the respective tube.
