There is a tremendous opportunity space for nanostructured materials to play a key role in next generation energy technologies.  Our research efforts focus on the fundamental study of optoelectronic properties of semiconductor nanocrystals; this work is inspired by the potential application of these materials in solar energy conversion and energy storage devices.

The semiconductor nanocrystals used in our work provide a diverse set of building blocks whose electronic and optical properties differ from their bulk counterparts due to the spatial wavefunction confinement.  This quantum confinement effect allows us to engineer the materials properties through simple adjustments in nanocrystal size, shape, composition, and surface chemistry.  In addition to their immense potential for technological applications, these materials also provide a material system to experimentally test fundamental quantum mechanical concepts.
