Research Interests

Applied Physics Research in the Van Duyne Group centers on plasmonics and single molecule/single nanoparticle spectroscopy. One goal is the development of ultrahigh vacuum, low temperature tip-enhanced Raman spectroscopy (TERS). TERS potentially combines the single molecule sensitivity of surface-enhanced Raman spectroscopy (SERS) with the atomic scale spatial resolution of the STM. Atomic resolution imaging has now been achieved using a plasmonic, noble metal tip under laser fluence. A second goal is to integrate femtosecond stimulated Raman spectroscopy (FSRS) with TERs to provide time-resolved vibrational structure information, both ground and excited state, of adsorbate molecules. The dream experiment is single molecule vibrational spectroscopy at atomically resolved single surface sites. Applications including dye-sensitized solar cells, catalysis, and ultrafast plasmonic devices are being explored at the single molecule/single site/single nanoparticle level. Electron beam lithography and atomic layer deposition are used to prepare the plasmonic  materials.  These projects are being conducted in collaboration with the Hersam, Seideman, and Schatz groups.
