Ag(111) surface reconstruction studied by optical second-harmonic generation

The optical second-harmonic reflectance of Ag(111) was studied as a function of the incident photon energy and the interfacial potential in an electrochemical environment. The behavior of the anisotropic contribution is consistent with a potential-induced surface reconstruction from C sub 3v to C su...

Beschreibung
Zusammenfassung:The optical second-harmonic reflectance of Ag(111) was studied as a function of the incident photon energy and the interfacial potential in an electrochemical environment. The behavior of the anisotropic contribution is consistent with a potential-induced surface reconstruction from C sub 3v to C sub 3 under conditions of positive surface charge.
