low-energy electron diffraction

Low-energy electron diffraction (LEED) is a technique used in surface science to study the arrangement of atoms on solid surfaces. By directing low-energy electrons at a surface, the electrons scatter off the atoms, creating diffraction patterns. Analyzing these patterns helps researchers determine the surface structure, such as the positions of atoms and the regularity of their arrangement. LEED is valuable in understanding material properties, surface reactions, and designing new materials by providing insights into how the atomic structure influences behavior at the surface level.
