Our research interests are in nanoscale investigations of physical and chemical systems. We utilize scanning tunneling microscopy (STM) to image and spectroscopically characterize materials on an atom-by-atom or molecule-by-molecule basis. Our current research studies focus on understanding the electronic structure of correlated electron materials and how this structure evolves with temperature near temperature-induced phase transitions.
We currently have two scanning tunneling microscopy setups:
1) We have a near room temperature (~270 – 400 K) variable-temperature scanning tunneling microscope which operates at atmospheric pressure in a nitrogen gas environment.
2) Our second system is an RHK Pan head designed STM. We recently implemented a ultra-high vacuum system for our microscope and have future plans to go cryogenic.
