Growth from below: bilayer graphene on copper by chemical vapor deposition. New Journal of Physics, 14, 093028.1367-2630https://hdl.handle.net/10877/14437We evaluate how a second graphene layer forms and grows on Cu foils during chemical vapor deposition (CVD). Low-energy electron diffraction and microscopy is used to reveal that the second layer nucleates and grows next to the substrate, i.e., under a graphene layer. This underlayer mechanism can facilitate the synthesis of uniform single-layer films but presents challenges for growing uniform bilayer films by CVD. We also show that the buried and overlying layers have the same edge termination.Text9 pages1 file (.pdf)enbilayer graphenecopperchemical vapor depositionsingle-layer filmsbilayer filmsIngram School of EngineeringArticlehttps://doi.org/10.1088/1367-2630/14/9/093028This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.
