Abstract

In this chapter the experimental results on adsorption of bromide on Ag(100) surface is described.

A sharp CV peak at −0.75 V (Ag/AgCl) corresponding to a disorder-order phase transition is, like with Ag(100)-Cl, also preceded by a broad peak. In the ordered c(2 × 2) phase, the bromide anions reside in fourfold hollow sites and cause a buckling of the second Ag layer. The concentration dependence of the lateral interactions, as revealed by Monte-Carlo simulations, indicates a change in charge state with coverage (and, thus, potential) of the adsorbed bromide [1, 2, 3, 4, 5, 6, 7, 8, 9], similar to Br/Cu(100), see Chap.  184[ https://doi.org/10.1007/978-3-662-53908-8_184].
