摘要： In order to determine the structure of complex and/or stepped surfaces that are very difficult to or even beyond the capability of the full dynamic low-energy electron diffraction calculation, recently we have proposed the quasi-kinematic low-energy electron diffraction (QKLEED) approach and employed it to solve the structure of some important surfaces such as Si(111)-(31/2×31/2) R30°-Al and Si(111)-(31/2×31/2) R30°-Ag. In the present paper, following the highlights of QKLEED we give the latest application of it, i.e., the structural determination of the Si(111)-(31/2×31/2) R30°-Au, Si(111)-(31/2×31/2) R30°-Sn, and Pd(001)-c(2×2)-Mn surfaces.
