Research Interests

• Atomic scale surface chemistry and the application of scanning tunneling microscopy to molecule-molecule and molecule-surface interactions.
• Applications of atomic force microscopy, including electrical and tribological characterization of surfaces, self-assembled molecular films, and wetting properties of surfaces.
• Mechanical and electrical characterization of nanostructures, and self-organizing interactions between nanostructures and substrates.

• Instrumentation development for nanomaterial characterization and surface science, including scanning probe microscopes, probe development and in situ manipulation and analysis.

Current projects

• Fundamental surface chemistry of metals by STM (with Miquel Salmeron, Foundry/LBL MSD)
  • Electronic contribution to friction on GaAs: An atomic force microscope study
    The electronic contribution to friction at semiconductor surfaces was investigated by using a Pt-coated tip with 50 nm radius in an atomic force microscope sliding against an n-type GaAs(100) substrate. Learn more
