Metal-adsorbate-induced Si(111)-(1×3) reconstruction

Abstract
The (1×3) phases generated by the adsorption of silver and alkali-metal atoms on the Si(111)-(7×7) surface are confirmed as a substrate reconstruction through the measurements of low-energy electron diffraction I-V curves for the (1×3) structures. The metal adsorbates which induce the (1×3) reconstruction are all at coverages below (1/3 and have no long-range order.
