摘要： In an embodiment, a method includes forming a first diamond layer on a substrate and inducing a layer of graphene from the first diamond layer by heating the substrate and the first diamond layer. The method includes forming a second diamond layer on top of the layer of graphene and applying a mask to the second diamond layer. The mask includes a shape of a cathode, an anode, and one or more grids. The method further includes forming a two-dimensional cold cathode, a two-dimensional anode, and one or more two-dimensional grids by reactive-ion electron-beam etching. Each of the two-dimensional cold cathode, the two-dimensional anode, and the one or more two-dimensional grids includes a portion of the first diamond layer, the graphene layer, and the second diamond layer such that the graphene layer is positioned between the first diamond layer and the second diamond layer.

摘要： In an embodiment, a method includes producing a mixed feedstock of at least three halogenated monomer feedstocks. A first of the at least three halogenated monomer feedstocks includes an SP3 carbon, a second of the at least three halogenated monomer feedstocks includes an SP2 carbon, and a third of the at least three halogenated monomer feedstocks includes at least two SP1 carbons. The method further includes producing a polyorbital-hybrid pre-ceramic polymer comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon. The polyorbital-hybrid pre-ceramic polymer is produced by reducing the mixed feedstock such that one or more halogen atoms are removed from the mixed feedstock. The method also includes fabricating the polyorbital-hybrid pre-ceramic polymer into a greenware form and producing a polyorbital-hybrid ceramic carbon comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon. The polyorbital-hybrid ceramic carbon is produced by thermolyzing the polyorbital pre-ceramic polymer.

摘要： In an embodiment, a system includes a three-dimensional (3D) printer, a neutral feedstock, a p-doped feedstock, an n-doped feedstock, and a laser. The 3D printer includes a platen and an enclosure. The platen includes an inert metal. The enclosure includes an inert atmosphere. The neutral feedstock is configured to be deposited onto the platen. The neutral feedstock includes a halogenated solution and a nanoparticle having a negative electron affinity. The p-doped feedstock is configured to be deposited onto the platen. The p-doped feedstock includes a boronated compound introduced to the neutral feedstock. The n-doped feedstock is configured to be deposited onto the platen. The n-doped feedstock includes a phosphorous compound introduced to the neutral feedstock. The laser is configured to induce the nanoparticle to emit solvated electrons into the halogenated solution to form, by reduction, layers of a ceramic comprising a neutral layer, a p-doped layer, and an n-doped layer.
