We present a study of rubidium adsorption on the Si(111)-() surface and the related Rb-induced reconstructions as a function of deposition temperature and Rb-coverage via scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED). Sample analysis via LEED allowed to observe for the first time a Rb/Si(111)-() reconstruction. STM allowed to obtain the first real space characterization of the Rb/Si(111)-() surface. In addition, STM provided a direct and local information on the surface arrangement as well as further insight on the interactions between Si and Rb atoms and on the growth dynamics.

Abstract

We present a study of rubidium adsorption on the Si(111)-() surface and the related Rb-induced reconstructions as a function of deposition temperature and Rb-coverage via scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED). Sample analysis via LEED allowed to observe for the first time a Rb/Si(111)-() reconstruction. STM allowed to obtain the first real space characterization of the Rb/Si(111)-() surface. In addition, STM provided a direct and local information on the surface arrangement as well as further insight on the interactions between Si and Rb atoms and on the growth dynamics.
