Choi Department of Chemical Engineering, University of Virginia Hybrid inorganic-organic nanomaterials as building blocks for designer solids and their applications in optoelectronic devices Tunable optoelectronic properties of hybrid inorganic-organic nanomaterials provide unique opportunities for science and technology. The degree of quantum confinement and collective electronic interaction in these materials can be readily tuned by controlling their synthesis and self-assembly processes. This enables fabrication of 'designer solids' with programmable optoelectronic properties tailored for specific scientific studies and technological applications. In this talk, I will discuss colloidal quantum dots and metal-organic perovskites, two of the most promising building blocks for designer solids. Both material systems exhibit intriguing properties tunable by design while looking set to revolutionize the field of solution processed optoelectronic devices. Bio: Joshua J. Choi received B.E. in Chemical Engineering from Cooper Union and Ph. D. in Applied Physics from Cornell University (Advisors: Tobias Hanrath and Frank W. Wise). He then performed postdoctoral research at the Department of Chemistry, Columbia University (Advisor: Jonathan S. Owen). He joined the faculty of the Department of Chemical Engineering, University of Virginia as a assistant professor starting in August, 2014.
