✦ Synopsis

Ž . Ž . The changes of atomic structure and the coverage of binary metals Bi,Sb at the Si 111 surface induced by thermal Ž . Ž . annealing have been studied by means of low energy electron diffraction LEED , Auger electron spectroscopy AES , and Ž . Rutherford backscattering spectrometry RBS techniques. It is shown that Bi and Sb form surface alloy of 63 =63 Ž . structure. Moreover, coaxial impact-collision ion scattering spectroscopy CAICISS has been used to determine the atomic Ž . Ž . Ž . Ž . structures of the Bi,Sb rSi 111 surface. The structural model for the Si 111 63 =63-Bi,Sb surface is proposed on the basis of the polar-and azimuth-angle's dependence of the Si, Bi, and Sb intensities.
