Organic Photodetectors and Electrochemical Transistors
My current research includes near-infrared and short-wave infrared organic photodetectors (OPDs) and organic electrochemical transistors (OECTs).
For OPDs, I focus on molecular and interface engineering, donor/acceptor interfaces, charge-blocking layers, and suppression of reverse-bias leakage while preserving photoresponse. For OECTs, I investigate volumetric capacitance, doping efficiency, and mixed ionic-electronic transport in conjugated polymers.
Seung Hyun Kim is a Postdoctoral Research Associate in the Department of Chemistry at the University of North Carolina at Chapel Hill, working under the guidance of Prof. Wei You. He earned his Ph.D. in Chemical Engineering at Pohang University of Science and Technology (POSTECH) under the supervision of Prof. Kilwon Cho.
His research focuses on conjugated polymers and organic semiconductors, with particular emphasis on structure-property relationships, charge transport, mechanical deformation, molecular and interface engineering, organic photodetectors, and organic electrochemical transistors.
