Focus

Chemical synthesis and assembly of nanostructured electronic and electrochemical materials, processing-structure-property relationships, energy and electronic devices.

Research

Structuring materials on the nanoscale presents new opportunities to develop functionality not found in homogeneous, single-component materials. Energy devices, in particular, demand materials with complex combinations of properties that can also be processed at low cost and on large scale. Research in the Milliron group is motivated by new concepts for high performance electrochromic smart windows, batteries, and photovoltaic cells that take advantage of the unique optical, electronic, and processing characteristics of colloidal nanocrystals and other nanoscale building blocks.

To develop innovative energy materials and devices, we use solution-phase chemistry to create nanocrystals and inorganic clusters and to assemble these into mesoscale architectures. We are actively investigating the chemistry and physics of doped metal oxide nanocrystals with infrared plasmonic resonances and high electronic conductivities. Anionic metal chalcogenide and metal oxo clusters are another class of building units we employ to construct multi-component inorganic composites, mesoporous networks, and hybrid mesostructures. Transport of electrons and ions through these materials is found to be strongly influenced by the ubiquitous heterogeneous interfaces. The atomic and nanoscale structure responsible for these transport phenomena are probed by a combination of electron microscopy, x-ray diffraction, and optical and x-ray spectroscopies under both static and in situ conditions, illuminating new design strategies for functional materials and devices. Ultimately, we apply these lessons to create novel solutions to cost and performance challenges critical to realizing next generation energy technologies.
