A systematic study of the Cu-catalyzed chemical vapor deposition of graphene under extremely low partial pressure is carried out. A carbon precursor supply of just PCH4 ∼ 0.009 mbar during the deposition favors the formation of large-area uniform monolayer graphene verified by Raman spectra. A diluted HNO3 solution is used to remove Cu before transferring graphene onto SiO2/Si substrates or carbon grids. The graphene can be made suspended over a ∼ 12 µm distance, indicating its good mechanical properties. Electron transport measurements show the graphene sheet resistance of ∼ 0.6 kΩ/□ at zero gate voltage. The mobilities of electrons and holes are ∼ 1800 cm2/Vs at 4.2 K and ∼ 1200 cm2/Vs at room temperature.
