Formation of two-dimensional graphite islands on the Pt 110/ 1=2/ surface

The formation of thin carbon overlayers at temperatures above 6008C has been studied on the Pt 110. 1=2.surface by Scanning Tunneling Microscopy STM., PES and Low-Energy Electron Diffraction LEED.. Their graphitic character is evidenced through the binding energy of the C1s core-level, the LEED pattern observed and the atomic structure resolved on the islands. The orientation of the graphite layers is determined to be C 1010:parallel to the Ptw110x direction. Their thickness and the nature of the substrate are discussed below. q2000 Elsevier Science B.V.
