LEED (Low Energy Electron Diffraction)

LEED, or Low Energy Electron Diffraction, is a technique used by scientists to study the surface structure of materials, particularly crystals. It involves directing a beam of low-energy electrons at the material's surface. These electrons bounce off and create a diffraction pattern that reveals the arrangement of atoms on the surface. Because the electrons have low energy, they are sensitive to only the top atomic layer, providing detailed information about surface structure. LEED is valuable in materials science and surface chemistry for understanding surface behaviors and properties.
