Dr. Duncan Weathers investigates experimentally the widely-applied process of sputtering, which might be described as "atomic sand blasting" in which atoms are removed from a surface by the impact of energetic atoms or ions. He uses the technique of Resonance Ionization Spectroscopy for his sputtering analysis.
