Current Research

I lead the Quantum Dot Team's efforts in colloidal nanomaterial synthesis. This includes the development and refinement of syntheses of semiconductor, metal and hybrid nanocrystals for applications ranging from photovoltaics and sensors, to light-emitting diodes and lasers. Our team is especially focused on the synthesis of complex nanostructures, including heterostructured, shape-controlled and impurity-doped nanocrystals, that display advanced physical phenomena and unique regimes of carrier control, particularly within optoelectronic devices. Areas of current interest include:

  • Narrow band-gap semiconductor nanocrystals for use in "Third Generation" solar cells
  • Heterostructured semiconductor nanocrystals that demonstrate unique carrier behavior regimes, such as ultra-long single-exciton lifetimes and suppressed Auger recombination
  • Semiconductor nanocrystals and nanoheterostructures doped with metal impurities to create novel magnetic, optical and magneto-optical functionality
  • Metal and semiconductor nanorods and platelets
  • Hybrid metal/dielectric/semiconductor and metal/semiconductor nanosuperstructures for plasmonic enhancement of light-nanocrystal and nanocrystal-nanocrystal interactions
