Research
Vanadium oxide nanowires assembled in a field-effect transistor geometry by AC dielectrophoresis.
Synthesis and surface chemistry of oxide nanoparticles; directed assembly and device integration of nanoparticles, nanowires, and carbon nanotubes; functional nanocrystal films for gate dielectric and photovoltaics; raman spectroscopy and XANES characterization of nanomaterials.
Since starting at UB in the fall of 2007, our research interests are focused on:
- The synthesis of HfxZr1-xO2 nanoparticles and their assembly into ordered thin films and superlattices for capacitor applications.
- The controlled synthesis of VOx nanowires and their integration into transistor geometries.
- The chemical functionalization of graphene with semiconductor nanoparticles for optoelectronics applications.
- The synthesis of CeO2-Au composite nanoparticles from organometallic precursors for catalytic applications.
We are especially interested in understanding the role of finite size effects in influencing the individual and ensemble electronic properties of nanomaterials. Towards this end, we use a variety of techniques for detailed structural characterization, focusing primarily on Raman spectroscopy and X-ray absorption spectroscopy approaches.
Raman microprobe system with multiple laser excitations; Malvern zetasizer for particle size analysis and zeta potential measurements.
