Low-Energy Ion Scattering from the Si(001) Surface

Abstract

The structure of a clean Si(001) surface has been studied by a specialized technique in low-energy ion scattering spectroscopy. It has been found that (1) the surface is dimerized, and (2) the intradimer atomic distance parallel to the surface is 2.4 \ifmmode\pm\else\textpm\fi{} 0.1 \AA{}.
