Determination of Ag submonolayer structures on Pt(111) from simulation and data of He scattering experiments

► The paper deals with interpretation of He scattering data from Ag grown on Pt(111). ► Under the considered conditions, Ag is supposed to deposit commensurately, layer by layer. ► A parametric model is built of the lateral interaction potential. ► Growth is simulated by means of an ad hoc thermodynamic Monte Carlo implementation. ► The model parameters are adapted to fit the experimental data in a wide range of conditions.
