Structure Analysis of Monolayer Graphite on Ni(111) Surface by Li⁺-Impact Collision Ion Scattering Spectroscopy

Precise control of layer number in graphene grown on Ni(111)

“…No obvious difference in the diffraction pattern is also seen before and after exposure. This is reasonable since it has been reported that the epitaxial graphene film with the commensurate 1  1 structure grows on the Ni(111) single crystal surface [4,5] and the increase of the amount of carbon after benzene exposure is confirmed by the AES measurements as discussed below. Figure 2 (a) shows evolution of the AES spectra during benzene exposure.…”

Precise control of single- and bi-layer graphene growths on epitaxial Ni(111) thin film

“…Considering the above analysis of the C KLL Auger spectra from the synthesized graphitic carbon, no obvious changes in the RHEED pattern and in the sharpness of the streaks during benzene exposure can be interpreted as the epitaxial growth of graphene with the commensurate 1 Â 1 structure on the Ni(111) surface, as reported for a Ni single crystal. 15,16 It is particularly notable that the relative number of carbon atoms, R, at 60 L and 1 Â 10 5 L exposures agrees well with that expected for SLG and BLG epitaxially grown on the Ni(111) surface, because two carbon atoms belonging to two triangular sublattices of graphene sit on the nickel atom in the epitaxial SLG on Ni(111) and twice the number of carbon atoms exists in BLG compared to SLG. From this viewpoint, the decrease (0-30 L exposure) and increase (30-60 L exposure) of the RHEED specular beam intensity with exposure as observed at the initial stage (see Fig.…”
