Abstract: Epitaxial graphene fabried by thermal decomposition of the Si-face of silicon carbide (SiC) forms a defined interface to the SiC substrate. As-grown monolayer graphene with buffer layer establishes an ohmic interface even to low-doped (e. g. [N] ≈ 10 15 cm-3) SiC, and a specific contact resistance as low as ρ C = 5.9×10-6 Ωcm 2 can be achieved on highly n-doped SiC layers.

Chemical vapor deposition - Wikipedia
Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit.
