Abstract

The Al(111)-(4 × 4)-Na structure formed by adsorption of Na on Al(111) at low temperature is studied by surface extended X-ray absorption fine structure (SEXAFS). Analysis of the SEXAFS measurements shows that the adsorbed layer is quasihexagonal close-packed and slightly compressed, with a nearest-neighbour Na-Na bond length of 3.70 ± 0.03 Å. Na atoms are adsorbed in 3 different adsorption sites with roughly equal Na-Al bond lengths of 2.8 Å but different perpendicular distances from the surface. Thus the Na layer is not strictly planar.
