Epitaxial Growth Template Using Carbon Buffer on Sublimated SiC Substrate (Pseudo Graphene)

Apparatus, systems, and methods for forming semiconductor materials (e.g., using nanofabrication) are generally described. In one example, a method comprises formation of a carbon buffer layer on a first substrate and a graphene layer on the carbon buffer layer, followed by removing the graphene layer so as to expose the carbon buffer layer and form a fabrication platform, and after removing the graphene layer, forming a first epitaxial layer directly on the carbon buffer layer covalently bonded to the first substrate, wherein the first epitaxial layer comprises a semiconductor. In one example, a method comprises forming an epitaxial layer directly on a carbon buffer layer that is covalently bonded to a substrate, wherein the epitaxial layer comprises a semiconductor, and wherein the carbon buffer layer is a pseudo-graphene layer.
