摘要：
Low-energy electron diffraction (LEED) have been used to determine the Cu(0 0 1)-c(4 x 4)-Sn structure formed at 300 K. It is demonstrated that a structural model suggested by scanning tunneling microscopy observations is correct: The model consists of one substitutional Sn atom and four Sn adatoms in the unit cell. Optimum parameters of the determined c(4 x 4) structure reveal that Sn adatoms laterally are displaced by 0.30 angstrom away from ideal fourfold-hollow sites along the (100) directions. It is proposed that such displacements of the Sn adatoms cause the formation of a network of octagonal rings on Cu(0 0 1). The substitutional Sn atom is located at each center of the octagonal rings. The formation conditions of the network are discussed. (C) 2010 Elsevier B.V. All rights reserved.
