Abstract : Li and K adsorption on the Si0012x1 surface has been investigated by field ion-scanning tunneling microscopy FI-STM. The STM images have shown that at the initial stage of adsorption Li K atoms 1 adsorb on top of one of the dimer forming Si surface atoms and stabilize asymmetric buckled dimerization and 2 form linear chains, perpendicular to the substrate 2x1 dimer rows. Our observations suggest that alkali metal adsorption on the Si0012x1 surface may be significantly different from the conclusions of earlier reports.
