Formation of two-dimensional graphite islands on the Pt(110)(1×2) surface

The formation of thin carbon overlayers at temperatures above 600°C 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 p...

Description
Summary:The formation of thin carbon overlayers at temperatures above 600°C 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〈101̄0〉 parallel to the Pt[11̄0] direction. Their thickness and the nature of the substrate are discussed below.
