Abstract: | We performed detailed molecular statics calculations of energy barriers for various adatom movements in the vicinity of small
island on (111) surfaces of Pt and Rh using Rosato-Guillope-Legrand interatomic potential. We found that for both systems
the exchange processes are energetically favorable in comparison with direct jumps of an adatom. We observed that Ehrlich-Schwoebel
barriers for exchange decrease significantly on small islands in comparison to single step on the surface. A comparison of
both materials is presented.
Presented at the VIII-th Symposium on Surface Physics, Třešt’ Castle, Czech Republic, June 28 – July 2, 1999.
