The study of the stretching mode of Li, Na and K on various Cu surfaces show that the force constant of the adsorbate-surface bond depends neither on coverage nor substantially on the particular type of alkali atom. On the Cu(110) surface the spectra also infer that the (1 × 2) reconstruction may be induced by a local coverage less than 0.03 monolayers.

Abstract
The study of the stretching mode of Li, Na and K on various Cu surfaces show that the force constant of the adsorbate-surface bond depends neither on coverage nor substantially on the particular type of alkali atom. On the Cu(110) surface the spectra also infer that the (1 × 2) reconstruction may be induced by a local coverage less than 0.03 monolayers.File in questo prodotto:
