Surface lattice structure

Surface lattice structure Density of active surface atoms and reactivity of the surface determined by the crystalline orientation of silicon/electrolyte interface... 

Figure 24. Schematic illustrations of the conditions of surface lattice structure (a) amorphous-like surface with no identity of orientation, (b) surface with kinks, steps and terraces characteristic of certain crystalline orientation and (c) surface with no identity of the lattice structure of the crystal due to the coverage of an amorphous oxide film. 

The specific interactions between a water molecule and the metal atoms. The pair interaction H2O-M is further modified by the metal surface lattice structure and by defects and the electrons in the metal, as discussed earlier. 

Fig. 2 The low-index planes (100), (110) and (111) of the fcc-crystal (a-c), and the corresponding surface lattice structures. Reproduced in part with permission of the author [1]...

Atomic scale roughness in terms of the density of kinks sites and steps relative to surface atomic density determines effect of surface lattice structure on the rate of reactions when the roughness is low relative to atomic density the reactions show a high degree of anisotropicity and when it is high the reactions tend to be isotropic.

V. is used to accelerate the positive ions which strike the crystal face. Properly spaced shields and electrical potentials prevent other metals from being sputtered onto the face of the crystal. After the ion bombardment, the crystal is annealed at 500° for a few minutes to remove argon and restore the surface lattice structure.
