Abstract

Profile imaging observations of clean palladium surfaces suggested that surface diffusion occurred by the slip of surface Shockley partial dislocations resulting in the depletion of material from the surface. The formation of PdO patches under strong electron irradiation and the epitaxial orientation relationships which developed between the oxide and the Pd matrix were studied at the atomic scale. The newly formed PdO crystals were not usually stable against further intense irradiation. Their disintegration as well as depletion has been considered in terms of the mechanical behavior of PdO crystals.
