Abstract

Single well-ordered graphene layers can be prepared on a number of metal surfaces. The structures exhibit in most cases, a Moire pattern in the scanning tunneling microscopy images with large modulation periods. The modulation arises from the lattice mismatch and the interaction with the substrate. A few structures have been analyzed by LEED. The results are reported and compared to the data from X-ray measurements and density functional theory calculations. The description of the 2-D modulation functions by Fourier coefficients and the restrictions due to the p3m1 symmetry of the structure is shortly summarized.
