Low-energy electron diffraction with signal electron carrier-wave wavenumber modulated by signal exchange-correlation interaction

Low-energy electron diffraction (LEED) is considered as elastic electron-atom scattering (EEAS) operating in a target crystal waveguide, where signal carrier wave wavenumber modulated by exchange-correlation (XC) interaction. A potential designed using KKR (Korringa-Kohn-Rostoker) muffin-tin (MT) model built on overlapping MT spheres that implement atoms with double degree of freedom, radius and level. An XC constructed Sernelius's many-particle theory self-energy. EEAS phase shifts are derived from Dirac's differential equations, four recent LEED investigations recalculated: Cu(111) + (3 √ 3 × 3)R30° -TMB, TMB = 1,3,5-tris(4-mercaptophenyl)-benzene chemical formula C24H15S3; Ag(111) (4 4)-O; (7 3)rect-SO4; Ru(0001) ( -Cl. Our generate substantially improved reliability factors, we report the first confirmation self-energy experiment.
