Structure maps of surface structures
The adatom positions of adsorbates like A = H, Se Xe on (100) or (111) surfaces of bcc or ccp metals and related compounds like hcp metals, NaCl or ZnS form a square, hexagonal, honeycomb or Kagome net. The ordered structures can be characterized by the self-coordination numbers of nearest, next-nea...

The adatom positions of adsorbates like A = H, Se Xe on (100) or (111) surfaces of bcc or ccp metals and related compounds like hcp metals, NaCl or ZnS form a square, hexagonal, honeycomb or Kagome net. The ordered structures can be characterized by the self-coordination numbers of nearest, next-nearest and third neighbors T-1, T-2, T-3 and the T-1, T-2 values plotted in structure maps for a constant ratio of vacant/occupied sites. Most experimental structures have a single coordination of all A atoms. The interactions between A atoms are attractive for chains of A atoms with T-1 = 2 and repulsive for T-1 = 0 or T-1 = T-2 = 0. The structures with intermediate T-1, T-2 values can be characterized by sequences of structural units like squares or hexagons with a different occupation of the corners by A atoms. |
