摘要：

Small, three-dimensional Pd clusters (d < 5 nm) deposited under UHV on two different single crystal surfaces (graphite and MoS2) are imaged with atomic resolution, both in air and in UHV, using scanning tunneling microscopy (STM). We show that a complete characterization of the morphology of the cluster can be achieved: three-dimensional shape; azimuthal orientation on the substrate; and arrangement of atoms on lateral facets. These results are in good agreement with those obtained from TEM observations on large particles (d > 10 nm). Some limitations of STM for such studies are discussed. (C) 1997 Elsevier Science B.V.
