This paper describes how the authors have used the tunneling microscope to characterize the adsorption of potassium on the Si(001)-2x1 surface. At submonolayer coverages, the authors have observed the formation of alkali metal chains that run perpendicular to the substrates dimer rows. At this coverage, the potassium atoms have been observed to adsorb onto a variety of different sites. At the saturation coverage of one monolayer, the alkali metal atoms become ordered, with the one-dimensional chains running parallel to the substrate dimer row direction.
