Exotic quantum charge transport in nano particle materials

Gold nanoparticle + molecule assemblies can exhibit electrical behaviours that are tunable through choice of molecule, assembly architecture, etc. Recently, we have been studying an insulator-to-metal transition in these systems, where the assemblies exhibit exotic quantum phenomena.

Conductance detection

In addition to questions in fundamental physical science, we are interested in methods and tools for analytical applications. A current focus is advancing conductance detection for chromatography and benchtop applications.
