A scanning tunneling microscopy study of metal films and supported gold particles

A new type of Scanning Tunneling Microscope (STM) was designed and constructed to study the surface morphology of small catalyst particles. This is the first application of the STM in the study of supported metal particles. The STM was used to study the surface morphology of Au/Pd films that were sputter deposited onto mica and subsequently sintered in air, as well as equilibrium gold particles formed and supported on graphite. New structures were observed on both the film and particle samples. The surfaces are very rough on the nanometer scale range that the STM can easily resolve.
