Materials Science and Engineering for the 1990s: Maintaining Competitiveness in the Age of Materials
far behind research groups in West Germany in the use of these techniques. Exciting new surface physics is coming from elastic and inelastic scattering experiments, for example, the soliton-like reconstruction of the (111) surface in gold, and the observation of a soft phonon on the (100) surface in tungsten that might be related to a reconstruction. At present, U.S. experimental physicists are just watching.
