DETAILED DESCRIPTION - The electronic device comprises a graphene layer, a planar hexagonal boron nitride (hBN) layer that is operably associated with the graphene layer and forms a functional interface, a power source, a phosphor layer (38), and metal atoms intercalated in the hBN layer. The graphene layer is: an electronic circuit; and graphene circuit layers that are partially isolated from one another by the hBN layer; and configured as conductive traces that are electrically coupled to the power supply and intersect at address points (34). The interface is an insulative functional interface, a semiconductive functional interface, and a capacitative functional interface. The hBN layer is: positioned to electrically insulate the graphene layer; operable to conduct heat from the electronic device; and is configured as light-emitting semiconductors that are located between the conductive traces at address points. The power from the power supply applied to the address points is operable to cause light to emit from the light-emitting semiconductor. The light-emitting semiconductors are: doped hBN layers stacked on one another; and associated together in groups to form pixels. The phosphor layer is functionally associated with the light-emitting semiconductor, and is operable to emit colored light upon excitation by light from the light-emitting semiconductor. The light-emitting semiconductors of individual pixels include phosphor layers capable of emitting different color lights. The graphene layer and the hBN layer are: positioned in an alternating relationship, which forms the capacitative functional interface; and rolled together to form the alternating relationship. INDEPENDENT CLAIMS are included for: (1) a sensor chip; (2) a holographic storage device; (3) an integrated circuit interconnect; and (4) a surface acoustic wave filter.
