Abstract
The carbon K-edge EELFS, AES and LEED are measured for the carbidic an d the graphitic carbons on Ni(111) and Ni(100) surfaces. The nearest n eighbor C-C distance 1.44 Angstrom obtained from EXELFS for graphitic carbon on Ni(111) is in good agreement with that for crystalline graph ite. We newly find the hybrid surface of the carbidic and graphitic ca rbon overlayers on Ni(111) surface. The carbidic carbon on Ni(111) sho ws ELNES spectrum similar to that on Ni(100) surface.
