Profile picture

Assistant Professor of Chemical Engineering and Materials Science and Electrical Engineering-Electrophysics


  • Doctoral Degree, Materials Engineering, Massachusetts Institute of Technology
  • Bachelor's Degree, Seoul Nat'l University


Prof. Yoon joined the MFD faculty at the University of Southern California in 2011. Between 2007 and 2010, he was a Beckman Institute Postdoctoral Fellow at the University of Illinois at Urbana-Champaign and worked on Si and III-V single-crystalline nanomaterials for unusual format photovoltaic modules, radio-frequency electronics, near-infrared imagers, and solid state lighting/display devices. Prof. Yoon received his B.S. degree in Polymer Science from Seoul National University in South Korea, and Ph.D. degree in Materials Science and Engineering from the Massachusetts Institute of Technology, respectively. His doctoral work was focused on utilizing block copolymers to form highly ordered self-assembled photonic bandgap materials for their applications in optically-driven lasing and stimuli-responsive photonic devices.

Research Summary

Yoon group’s research aims to tailor and understand novel optical, electrical, thermal, and mechanical properties of inorganic single-crystalline semiconductor materials configured with top-down fabricated, programmable nano- or microscale features in ways that can maximize the performance and cost-effectiveness in applications using these materials. We also pursue to explore unconventional pathways to heterogeneously integrate them as synergistic building blocks into device- and circuit-level implementation on various substrates of interest including a thin sheet of plastics for constructing flexible and stretchable systems. Specific technological areas of interest include high performance, low cost photovoltaic and photoelectrochemical water splitting systems based on printed assemblies of nanostructured silicon and III-V materials, and skin-mountable or implantable microlasers based on released vertical cavity surface emitting lasers (VCSELs) for biointegrated optoelectronic sensors and actuators.
