Abstract:

A program directed toward a study of the Scanning Tunneling Microscope STM as a new instrument for examining and modifying surfaces at the atomic level. The STM has been developed to the point where it can be used routinely to record atomic surface structure and this technology has been successfully transferred to a commercial enterprise. The underlying technology can be used to mark surfaces on the scale of 100 A exploiting a variety of physical mechanisms. The writing speeds and signal-to-noise ratios in this new marking technology are suitable for high density storage systems.
