This study first reports the initial growth stages of sodium chloride (NaCl) on Ag(1Â 1Â 0) at room temperature. NaCl grows in bi-layer mode along its [1Â 0Â 0] axis and gives rise to (4Â ÃÂ 1) and (1Â ÃÂ 2) reconstructed domains for coverages lower than two monolayers (ML), a minimal thickness inducing a bi-dimensional closed film. In addition, a 10Â ML NaCl film has been examined by low energy electron diffraction (LEED). LEED analysis leads to the dissociation of the NaCl deposit in a few minutes. The NaCl dissociation implies Cl desorption from the surface and Na remaining on it. The residual Na is arranged in the form of a (2Â ÃÂ 1) surface reconstruction and is found to be strongly bounded to the Ag substrate. These findings have been established by using the X-ray photoelectron spectroscopy technique.
