STRAIN RELIEF AND Pd ISLAND SHAPE EVOLUTION ON THE PALLADIUM AND PALLADIUM HYDRIDE (100) SURFACE

摘要

The mesoscopic relaxation of small Pd islands on Pd(100) and PdH(lOO) surfaces is investigated on the atomic scale by performing. molecular statics calculations. A strong strain and stress inhomogeneity in islands and topmost layers of the substrate is revealed. An unusual size dependence of the shape of islands is discovered.
