Abstract
The growth of Pt(111) from its vapour phase is investigated by means of TEAS (thermal energy atom scattering) in a wide range of substrate temperatures: 100–800 K. The evolution of the in-phase He specular peak height during Pt deposition is studied in particular. At higher substrate temperatures ( T s > 500K), the in-phase peak height exhibits longlived temporal oscillations with a clearly asymmetric shape. This asymmetry, which increases with temperature, reveals substantial coarsening of the adatom islands during monolayer deposition, most likely due to Ostwald ripening processes.
