Image of FIG. 1.
FIG. 1.

(a) STM image of graphene/SiC at −1.5 V indicating monolayer and bilayer regions. Atomic resolution images of (b) monolayer region at –1 V and (c) bilayer region at –5 mV. The inset shows a image at high bias of −0.9 V and 0.22 nA revealing the hexagonal arrangement. (d) Spatially averaged spectra of monolayer and bilayer regions.

Image of FIG. 2.
FIG. 2.

STM image of EG after room temperature deposition of gold and annealing at 1000 K. (a) New surface structure due to the intercalation of gold atoms under the first MG (-derivative representation of the topography). The inset represents the three different regions zoomed in [(c)–(h)]: the black region corresponds to [(c) and (f)], the gray to [(d) and (g)], and the white to [(e) and (h)]. The topographic image (b) is a zoom of (a). (a): and (b): and , [(c)–(e)]: , , −110 mV, and respectively, and [(f)–(h)]: and .

Image of FIG. 3.
FIG. 3.

topographic images at −0.5 V of (a) “bilayerlike” region [the white region in the inset of Fig. 2(a)] and (b) a conventional bilayer graphene. (c) a theoretical model showing the Moiré pattern obtained by the superposition of a monolayer of gold and a monolayer of graphene, which results in a surface modulation as observed in (a). (d) Topographic image at −1 V and and map (inset) and (e) the corresponding STS measurement on the three region labeled 1 (undoped monolayer graphene), 2 (ostrich leather), and 3 (bilayerlike).
