Reconstructions of Elemental Metal Surfaces

2) Charges in surface layer atomic density Large-scale surface reconstructions producing changes in the surface layer density have been identified on several metal surfaces. Notably, as described in Chapter 1, the top layer of the (100) 

Another surface reconstruction that fits perfectly into this class of reconstructions is the so-called herring bone reconstruction of Au(lll) [104-108]. 

a uniaxial contraction along one of the 110 directions in the top layer leads to a layer with a higher density of atoms in it than the unreconstructed (111) surface and a surface unit cell of n x /i) (n = 22).
