Image of FIG. 1.
FIG. 1.

Atomic resolution STM images: (a) graphene on Ni(111) grown at , (b) graphene on Ru(0001) grown at , (c) graphene on Pt(111) grown at . Scan parameter: (a) , , (b) , , and (c) , . The inset is the corresponding LEED pattern of the sample. The beam energy is 60 eV. The height profile is taken along the line in (b) and (c), showing the corrugation of graphene on Ru(0001) and Pt(111).

FIG. 2.

The atomic model of graphene on Ni(111), Pt(111) and Ru(0001). Small atoms are graphene and big atoms are substrate atoms. (a) Graphene on Ni(111). The interfacial distance is 2.01 Å. (b) Graphene on Ru(0001). The distance is 2.13 Å and 3.79 Å. (c) Graphene on Pt(111). The distance is 3.31 Å.

FIG. 3.

(a) Sketch of thermoelectric measurement. The W tip is coated with indium. (b) The curve of graphene on Pt(111) at 330, 360, 390, and 420 K. (c) The curve of graphene on Ru(0001) at 450 K. It has two typical states: positive thermoelectric potential and negative thermoelectric potential. It show the variation from positive state (line 1) to negative state (line 2) when the tip approaches by a step.
