Materials Chemistry and Nanoscience

The faculty members employ diverse approaches in the synthesis, characterization and applications of advanced materials. Anne Kelley's group studies the vibrations (phonons) of semiconductor nanocrystals and how they are coupled to electronic excitations. David Kelley's group uses ultrafast optical spectroscopy to examine the optical and electronic properties of semiconductor nanoparticles that have potential applications in solar energy conversion and display technologies. Tao Ye's group focuses on the measuring and controlling surfaces and interfaces, which are increasingly important for as the sizes of materials scale down. Erik Menke's group fabricates and studies the photophysics of semiconductor nanowires for applications in solar energy conversion.  Alex Noy's group studies molecular transport and signal transduction across nanoscale interfaces and develops biomimetic nanostructures that facilitate the creation of bioelectronic devices and circuits.
