A tabulation and classification of the structures of clean solid surfaces and of adsorbed atomic and molecular monolayers as determined from low energy electron diffraction patterns

摘要: Abstract A tabulation is presented of the ordering characteristics clean and adsorbate-covered single crystal surfaces based on diffraction patterns observed with LEED (Low Energy Electron Diffraction). Over 3000 structures are classified by rotational symmetry substrate surfaces, important sub-classes which reflect recent directions studies. These include metallic monolayers, alloy organic overlayers, coadsorbed physisorbed high-Miller-index (stepped) surfaces. We review each sub-class, propose future investigations.
