Abstract

In this chapter the experimental results on adsorption of iodide ion on Au(111) surface is described.

Iodine adsorption from a dilute solution in methanol leads to a (√3 × √3)R30° structure at <0.33 ML coverage but at increasing coverage to a (p × √3) Moiré-like pattern with long-range height modulation [3].

In situ STM measurements in NaI and NaBr solution yield well-ordered monolayer structures: At low potentials and coverages <0.33 ML a (√3 × √3)R30° structure, and with increasing potential/coverage first a centered rectangular c(p × √3)R30° phase, also described as (3 × 3) structure, and then a “rotated hexagonal (rot-hex)” phase in the range between 0.3 and 1.4 V (RHE), due to increasing coverage and degree of compression [1, 2, 3, 4].
