Inorganic Chemistry/Materials Chemistry

The Owen group studies the inorganic chemistry of semiconductor and metal nanocrystals. We specialize in the kinetics and mechanisms of crystal formation as well as the structure and reactivity of colloidal crystal surfaces. These studies are aimed at describing the relationship between structure and electronic properties in nanocrystals and are leading to practical renewable energy technologies. We are particularly interested in solution-processed semiconductor films and catalysts that interconvert the energy in sunlight, electricity, and chemicals.
