Abstract
UHV scanning transmission electron microscope (STEM) was used to study the evolution of 55-atom icosahedral silver clusters. The experiments were performed on a UHV STEM known by the acronym MIDAS (Microscope for Imaging, Diffraction and Analysis of Surfaces). Silver nanoparticles were formed by evaporating Ag onto a pre-cleaned thin carbon film inside the UHV specimen preparation chamber attached to the MIDAS column. The icosahedral Ag particles can be identified by their unique nanodiffraction patterns. By measuring the sizes of icosahedral Ag particles in secondary electron or high-angle annular dark-field images we have been able to identify 55-atom Ag clusters.
