Physics Colloquium with Jiwoong Park

Two dimensional (2D) electron transport has been one of the most important topics in science and technology for decades. It was originally studied in 3D semiconductors and then continued in 2D van der Waals (vdW) crystals. In this talk, Park will start with the large-scale processes for generating 2D crystalline semiconductor films and superlattices that could be used to fabricate atomically thin integrated circuits. Then we will discuss more recent directions. He will discuss how we use these 2D materials to realize non-electronic “magical” 2D transport phenomena observed from phonons, photons, and mass, which could empower the development of 2D phononics, 2D photonics, and 2D mechanics. I will end with discussing how one can realize these properties using molecule-based 2D polymers and crystals.

Jiwoong Park a professor of Chemistry and Molecular Engineering at the University of Chicago. His research group is working on the science and technology of atomically thin crystalline materials and showed how to chemically synthesize and control 2D van der Waals crystals and molecular structures to produce real, large-scale materials useful for future applications.

He received a B.S. degree from Seoul National University (1996) and a Ph.D. from the University of California, Berkeley (2003; advisor: Prof. Paul McEuen). Before coming to the University of Chicago in 2016, he was a faculty member at Cornell University and a Rowland Junior Fellow at Harvard University. Park served as Associate Editor for Nano Letters (2017-23) and currently serves as Chair of the Department of Chemistry at UChicago.
