Optical response of the Cu(110)/electrolyte interface

Abstract

It is demonstrated that the angular variation of a positive peak at 2.2 eV in the reflection anisotropy spectrum (RAS) observed from the Cu(110)/electrolyte interface is consistent with its identification as a transition between surface states at the ̄ point of the surface Brillouin zone. The angular variation of a broad negative feature in the RAS spectrum is consistent with the major contribution to its intensity arising from transitions polarised along the principal axes of the Cu(110). The intensity of this feature varies with the potential applied to the Cu(110). © Published under licence by IOP Publishing Ltd 2011.
