Surface crystallography of clean platinum single crystals and adsorbed hydrocarbon overlayers studied by low energy electron diffraction
Technical Report
·
OSTI ID:7321306
The intensities of the low-energy electron diffraction (LEED) beams backscattered from the clean platinum (111) and clean, reconstructed platinum (100) surfaces are measured by a photographic technique. The LEED intensities are also measured for the ordered (2 x 2) hydrocarbon overlayers of acetylene, ethylene, methylacetylene and propylene as well as the ordered benzene overlayers adsorbed on the Pt (111) surface. The intensities are presented in an appendix in the form of normalized diffraction beam intensity versus incident electron energy (I-V curves).
