Abstract

The ability to perform atomic force and transmission electron microscopy on nanoscale Au clusters supported on the identical alpha -Al/sub 2/O/sub 3/ substrate has been demonstrated. Non-contact atomic force and transmission electron microscope images were used, in a complimentary manner, to determine: (i) the nanoscale structure of the alpha -Al/sub 2/O/sub 3/ substrate, (ii) the size distributions of cluster heights (AFM) and diameters (TEM) on alpha -Al/sub 2/O/sub 3/, (iii) the fraction of Au clusters imaged on different atomically-smooth substrates using non-contact AFM, and (iv) the surface induced deformation of Au clusters on alpha -Al/sub 2/O/sub 3/, MoS/sub 2/ and HOPG substrates. From these data, information about supported cluster shape and cluster-substrate interactions for these three substrates was obtained. (18 References).
