An epitaxial graphene growth on SiC substrates was achieved using hot filament chemical vapor deposition (HFCVD). Raman, SEM, AFM torsion resonance mode measurements, and EDS analyses have all been conducted on the produced graphene. HF cleaning of substrate surfaces allows for the production of high-quality few-layer and multilayer graphene layers, and their structures remain virtually indistinguishable from uncleaned substrates for extended growth times. Characteristics SiC graphene, formed by exfoliating monolayers of carbon from a wide-bandgap semiconductor substrate, shares many of the properties found in freestanding monolayer graphene. As such, SiC graphene can be utilized in many different applications; such as transistors for modern electronics; solar cells and energy storage; superconductors …
