Research activities

• Surface structure, electronic properties, and reactivity of bimetallic  surfaces by atomic-resolution scanning tunneling microscopy, electron diffraction, and synchrotron radiation.
• Mechanisms of electron- and photon-stimulated desorption of atoms and ions from surfaces (including charge transfer and energy transfer phenomena) using unique apparatus that  permits angle-resolved ion detection.
• Nucleation, growth, epitaxial structure and interfacial reactivity of ultrathin metal films on  oxide surfaces and on polymer surfaces using electron and ion spectroscopies, coupled with high resolution (sub-nanometer) electron microscopy.
