We present a graphene nanoribbon fabrication method based on a nanowire mask. Using a four-probe setup, single-layer nanoribbon (SLR) and bilayer nanoribbon (BLR) show low-frequency noise levels lower than (comparable to) the SLRs (BLRs) achieved by hydrogen-silsesquioxane based methods. Submicron channel SLR and BLR both show conductance quantization at 77 K, which suggests that quasi-one-dimensional quantum transport can be achieved. The conductance plateaus in BLR are less pronounced than those in SLR.
