摘要:
Using scanning tunneling microscopy, the changes in the morphology and atomic structure of the Si(111)5 root 3x5 root 3-Sb surface during Sb desorption have been studied. It has been found that the Si(lll)5 root 3x5 root 3-Sb surface phase does not have a definite composition. In attempting to explain the 5 root 3x5 root 3 long-range order stability in a wide Si and Sb coverage range it has been suggested that Sb atoms partially substitute for the boundary Si dimers in the basic 5x5 dimer-adatom-stacking-fault structure. A possible model of the Si(lll)5 root 3x5 root 3-Sb reconstruction satisfying this requirement has been proposed, (C) 2000 Elsevier Science B.V. All rights reserved.
