Abstract: The adsorption site, and adsorbate-substrate bondlength, has been investigated for the adsorption system Al(111)/Rb, using normal incidence standing x-ray wavefield absorption (NISXW), over a range of coverages from 0.12 to 0.33 ML including the ordered (2×2) and (√3×√3)R30° phases. By measuring both (111) and (1̄11) Bragg reflections in NISXW we obtain Rb–Al layer spacings in two real space directions and can therefore fully determine the adsorption structure by triangulation. For all phases we find adsorption in the atop sites, with a coverage-independent bondlength corresponding to an effective radius for the adsorbed Rb of 1.70±0.10 Å, significantly closer to the ionic (1.48 Å) than the metallic (2.43 Å) value. The NISXW results also show that the adsorbed Rb atoms have large vibrational litudes parallel to the surface which may be associated with the atop site adsorption.

Abstract: In this letter we present evidence from scanning tunneling microscopy studies in support of a recently proposed structural model for the indium-terminated c(8×2) surface of InSb(001). This structural model, by Norris and co-workers, is based on a surface x-ray diffraction study [Surf. Sci. 409, 27 (1998)], and represents a significant departure from previously suggested models for the c(8×2) reconstruction on any (001) surface of the common III–V semiconductor materials. Although filled state images of the InSb(001)-c(8×2) surface have previously been published, empty states image of sufficient quality to extract any meaningful information have not previously been reported. The observations are in excellent agreement with the recently proposed model for this surface reconstruction.
