a Schematic depicting the sheet resistance measurements of GGFF at different graphene growing periods. Period I: open circuit condition between isolated graphene domains, period II: connected circuit condition of continuous graphene films. b Sheet resistance as a function of growth time for GFFFs prepared using dichloromethane (orange) and methane (blue) precursors. The carbon supplies remained consistent in both systems. The pentagram points marked the time for the formation of full-coverage graphene films and the triangle points marked the time for reaching the sheet resistance of ~30 Ω sq−1. The error bars represent the standard deviations (n = 5). c Comparisons between the growth rates of graphene obtained in this work with those reported in literature21,25,39,40,41,42,43,44. d, e High-resolution TEM images on a TEM grid of dichloromethane- and methane-grown graphene obtained under the same graphene growth rate (growth parameters: H2/CH2Cl2 ratio of 8:1; H2/CH4 ratio of 1:5). Insets are corresponding selected area electron diffraction (SAED) patterns (scale bars: 5 n m−1).
