Oxidized surface of a tungsten sample has been used as a carrier for palladium and/or molybdenum clusters, prepared by vacuum deposition. Field electron emission microscopy has been applied to study these sandwich systems (Pd, Mo/WOx/W). In this work, nitrogen spill-over between neighbouring molybdenum and palladium clusters (islands) was demonstrated. The crystallographic orientation of these clusters has been studied by field ion microscopy.
