Popis:	The morphology of a Cu(110) surface after low coverage Pt atom deposition from the vapour phase is studied with thermal energy atom scattering (TEAS) in the temperature range of 200–800 K. Both cross section measurements and diffraction analysis reveal different structures. At low temperatures, isolated defects containing a metal adatom are observed. Between 350 and 650 K, experimental results suggest that these aggregates are dissociated, leaving behind them an almost flat surface patch with an incorporated Pt atom. Above 650 K, bulk dissolution of Pt occurs.
