Abstract

A strongly chemisorbed Hg species is observed following adsorption of Hg on Si(111) at 110 K. Photoemission intensities suggest that initial Hg adsorption occurs into subsurface sites. Mercury induces a √3 × √3 LEED pattern at moderate exposures (10-20 L) or upon annealing at 10 langmuir Hg exposures. At higher exposures (> 30 L), a LEED 1 × 1 pattern develops. Contrary to what is observed for mercury adsorption on several metal surfaces, some mercury atoms are still left on the Si surface even after flashing the crystal to 1250°C.
