Abstract
Pd particles were condensed under UHV on ZnO (001) thin films epitaxia lly grown on mica single crystals. The epitaxial relationships between Pd and ZnO lattices were determined by electron diffraction, (111) Pd //(001) ZnO and [11 (2) over bar] Pd//[100] ZnO. A tetrahedral shape o f the particles larger than 20 nm was observed, using weak beam dark f ield electron microscopy. After strong irradiation conditions, an evol ution of the structure nias observed, which could be due to the format ion of Pd-Zn alloy. (C) 1997 Elsevier Science S.A.
