    Grant Teams UVA ChE Lab with ODU Researchers to Investigate Quantum Dots

    August 19, 2020

    Associate professor of chemical engineering Joshua Choi recently received a National Science Foundation research grant titled “Collaborative Research: Nanoscale Charge Transfer in Quantum Dots Connected with Molecular Switches.” The project is a collaboration with Guijun Wang’s research group at Old Dominion University. Wang is a professor of chemistry and biochemistry.

    The research team will study differences in how electrons move between quantum dots (semiconductor nanoparticles with tunable optical and electrical properties) when the shape of molecules bridging the quantum dots changes. This research has a potential to advance the fundamental understanding of optical and electrical processes in nanoscale materials with broad implications for improving computing and memory devices that serve a range of needs.

    The Choi group’s collaboration with Wang and her researchers was seeded by a 4-VA grant that made it possible for the team to generate key preliminary results. 4-VA is a partnership among eight Virginia universities formed around four research and educational initiatives.

    The research activities covered by the $310,420 National Science Foundation grant also integrate educational efforts to improve recruitment, training and retention of students in science and engineering fields, especially among underrepresented groups at the University of Virginia and Old Dominion University.
