摘要：

We present a scanning tunneling microscopy study of incommensurate lattice formation in chemisorbed chlorine and iodine layers on Cu(1 1 1) under ultrahigh vacuum conditions. For halogen layers the transition from commensurate phase Cu(1 1 1)-(root3 x root3)R30 degrees -Hal to incommensurate one was found to pass through continuous development of striped domain walls separating the (root3 x root3)R30 degrees domains.
