Scanning Tunneling Microscopy (STM), with its ability to acquire atomic-scale images of solid surfaces, is our primary tool for investigating the physical properties and chemical reactivity of these surfaces:
- The importance of local surface environment and structure on chemical reactivity is measured using sequences of STM images acquired in situ during gas-surface chemical reactions. We acquire "stop motion" movies to study the effect of hydrogen-atom (JACS, JPC C, JPC C) and chlorine-atom (JCP, PCCP, JCP, JPC Letters) reaction with alkanethiol self-assembled monolayers.
- The structural and electronic properties of large, organometallic molecules will determine their suitability as components for molecular electronic devices. We record STM images of mixed-valence compounds and have shown that charge can be localized on a single metal center within a larger molecule.(JACS, JACS, JPC C, PCCP)
- The structure of self-assembled monolayers depends on both the molecule-molecule and molecule-surface interaction strengths, as well as on the kinetics of monolayer formation. We have studied monolayers and mixed monolayers of a variety of molecular species on metal surfaces, including fullerenes (Langmuir, Surface Science) and alkanethiols.(Langmuir, JPC C)
- Hydrogen bonds are widely used in supramolecular and surface chemistry to prepare complex structures through self-assembly. We investigate particularly complex assemblies that result from rapid solvent evaporation.(Nature, Chem. Communications)
- We develop and build hardware and electronics. Source files and build instructions can be found on our Open Hardware site.
