▎ 摘　　要

In this study, graphene was rapidly grown by chemical vapor deposition using a liquid cell for supplying methanol as a carbon source of graphene. To realize the rapid growth, methanol which is carbon-contained organic solvent was used instead of methane gas, a widely used carbon source for graphene growth. The graphene grown with the growth time as a variable was transferred to a SiO2/Si substrate with an oxide thickness of 300 nm to confirm whether it was grown with full coverage with an optical microscope. The results confirmed a full coverage in 0.5 min of growth. The Raman spectra also confirmed the G-peak position at 1585.0 cm(-1)and an intensity ratio of 2D/G at 2.3 or higher. Concerning electrical transport characteristics, at an induced carrier density of 1 x 10(12) cm(-2), the hole (mu(h)) and electron (mu(e)) mobilities were 1524 cm(2) V-1 s(-1)and 1528 cm(2) V-1 s(-1), respectively. Thus, our study confirmed that high-quality, large-area graphene can be grown within 0.5 min.
