Abstract

High-resolution images, multislice image simulation and image processing are used to study surface roughness in small metallic particles. The images of Pt particles on alumina substrates show displacements of the atomic columns that are shown to be due to local changes in thickness. It is concluded that surface roughness is present in Pt particles on Al₂O₃ and can be studied with these techniques.
