Nanoscale chemical imaging and spectroscopy

We are interested in identifying the unique chemical fingerprint of materials and mapping their chemical properties with nanoscale lateral resolution.

Our Team’s accomplishments

  • 2019-2024: Our NSF CAREER grant will support the development of new schemes for nanoscale infrared spectroscopy and polarized infrared spectroscopy

  • 2007-present: Explore the effect of multi-frequency AFM on the performance of nanoscale infrared spectroscopy
