Ka. Friedrich et Gl. Richmond, SURFACE 2ND-HARMONIC GENERATION STUDIES OF STEPPED AG(111) ELECTRODE SURFACES, Chemical physics letters, 213(5-6), 1993, pp. 491-497
The rotational anisotropy in the optical second harmonic response from
flat and stepped Ag electrode surfaces biased in an electrolyte solut
ion have been examined. Compared to the flat Ag(111) surface, the step
ped surfaces show a pronounced effect due to the lowering of the surfa
ce symmetry. The results are interpreted in terms of a pseudo mirror p
lane at these steps.
