Cluster Imaging

  • Klaus Sattler


Cluster beam analysis by time of flight mass spectrometry and simultaneous deposition on a support with subsequent imaging by a transmission electron microscope is described in the first part of the paper. 10–15 Å CsCl clusters, deposited onto glass substrates at room temperature, grow to small particles with thousands of angstroms in size. These results leaded to the use of an instrument with imaging capabilities on a much smaller size scale. The scanning tunneling microscope as a new tool for cluster research could be established. Using this instrument, gold and silver clusters on graphite have been imaged with atomic resolution. Diffusion and growth of individual clusters has been observed. Possible influences of the microscope on the deposited clusters are discussed.
