Title: Electronic Landscapes of Molecular Nanostructures: Mapping States for Charge Transfer with Pixel-by-Pixel Scanning Tunnelling Spectroscopy
Location: 67-3111 Chemla Room
My research career has centred around the use of Scanning Probe Microscopy techniques to learn about materials from a nanoscale view. My early research opportunities as an undergraduate at Dalhousie University exposed me to UHV STM manipulation of molecules on surfaces, and liquid AFM for probing biological samples. Having hands and eyes in the nanoworld facinated me then, and still does today. My MSc and PhD work in Peter Grutter's group at McGill University focussed on studying growth of organic semiconductors on insulating substrates by UHV nc-AFM to provide a foundation for molecular electronics studies. In my postdoctoral work at UC Berkeley with Mike Crommie, I used low-temperature UHV STM and STS to look at graphene nanostructures, and we found giant pseduomagnetic fields in strained grpahene nanobubbles. Now in my own group at UBC we apply these tools to understand how structure and electronic states relate by taking spectroscopic measurements on the nanoscale. We apply these methods to molecular systems, graphene and superconductors, and work to extend the SPM toolbox. I enjoy collaborative work, and am always interested in new materials.
