Two Dimensional Compressibility of Electrochemically Adsorbed Lead on Silver (111).

Abstract

We report the two dimensional compressibility of electrochemically deposited lead on silver (111). Measurements were made in-situ (in contact with solution) using grazing incidence x-ray scattering. Between monolayer formation and bulk deposition, the near neighbor distance of the lead monolayer decreases linearly with applied potential, (proportional to the chemical potential). Since the lead monolayer is in equilibrium with the lead in solution, the isothermal compressibility of the monolayer can be calculated and is 0.9 sq. A /eV. Implications of the highly strained monolayer on the wetting behavior of lead are discussed.
