Research

The underlying theme of our research is the unique combination of optical irradiation with solid-state NMR. Broadly, our research can be classified into four primary areas:

  1. Optically-enhanced NMR of semiconductors in bulk and low-dimensional heterostructures;
  2. Photoinduced structural changes (i.e., [2+2] cycloadditions) in materials which are candidates for optical memory and/or optical switches;
  3. Investigations into CO2 sequestration in various mineral structures
  4. Characterization of inorganic nanostructures, including Al and Ga nanoclusters


Our group possesses unique hardware that permits optical access at the NMR sample space, thereby allowing us to irradiate samples in situ. We are looking at a variety of materials via these methods, including:

  • III-V and II-VI bulk semiconductors; quantum wells, quantum wires, and quantum dots of the II-VI systems
  • Crystalline organic species, including some supramolecular complexes
  • Chalcogens (77Se, 125Te) in various forms, including clusters, II-VI nanoclusters, and some III-V passivating agents.
     

Our group, therefore, is developing expertise along several lines, including:

  • Characterization of low-dimensional semiconductors
  • Radio-frequency probe and hardware construction
  • Simulation of NMR spectra
