(a) Schematic of sample consisting of large-area monolayer CVD graphene film residing on a layered substrate comprising 525 μm high resistivity Si, 50 nm boron-doped poly- Si with n ≈ 2.6 × 1019 cm−3 and 165 nm Si3N4. Graphite and gold contacts are used for contacting the graphene film and the poly-crystalline Si film, respectively. (b) tiled optical ultra-high resolution image of CVD graphene sample on THz-transparent, layered substrate. (c) Raman characteristics of CVD graphene film, including representative spectrum, D/G and 2D/G distributions
