non-contact AFM and TEM.

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).
