Materials Chemistry and Nanoscale Electronics

The focus of our research is the controlled synthesis of well-defined nanoscale building blocks and their assembly and integration into functional devices. We are particularly interested in the rational design of nanomaterials that can be used as the active components in the next generation of electronic devices.

We are interested in designing new synthetic strategies to fabricate nanoparticles and nanowires with controllable dimensions and well-defined surface chemistries. One major thrust of our efforts will be to understand finite size effects in our nanostructures. This involves the use of a variety of spectroscopic and microscopic tools.

Raman spectroscopy and synchrotron-based X-ray absorption spectroscopy are of particular interest for characterizing nanostructures. Students will be exposed to a truly interdisciplinary environment and will acquire synthetic skills and experience with many different characterization tools and nanofabrication techniques.

Another area of interest is the assembly of ordered arrays and superlattices of nanoparticles by careful control of the surface chemistry and charge. We are also interested in the precise positioning and alignment of 1D nanostructures in device geometries. These 1D nanowire devices will be used in sensing and high- performance transistor applications. Some specific research areas include

The synthesis of Hf_xZr_1-xO₂ nanoparticles and their assembly into ordered thin films and superlattices for capacitor applications.
The controlled synthesis of VO_x 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.
