摘要：

The adsorption of iodine on Cu(110) has been studied with scanning tunnelling microscopy and low energy electron diffraction. A simple commensurate structure c(2 x 2) is formed at the coverage 0 = 0.5 ML. Further adsorption of iodine leads to the uniaxial compression of the c(2 x 2) structure along [110] direction of the substrate. STM data show that the compression includes the formation and development of striped domain walls. At the saturation point (0 = 0.63 ML), iodine forms a uniformly compressed quasi-hexagonal structure, (c) 2005 Elsevier B.V. All rights reserved.
