A study of the growth and mobility of Pd nanoclusters on WO3(001) by scanning tunnelling microscopy

Abstract:

The growth of Pd on WO3(001) at room temperature has been studied by scanning tunnelling microscopy. Thermally evaporated Pd grows on WO3(001) c(2 × 2) as truncated hemispherical nanoparticles whose mean diameter and height increase with increasing Pd coverage. There is some indication of preferential nucleation of clusters at step edges and at boundaries between c(2 × 2) and p(1 × 1) rafts on the (001) surface. Thermal annealing of nanoparticle covered surfaces at 873 K leads to agglomeratio...
