Research

I investigate how molecular structure, backbone rigidity, molecular packing, and thin-film microstructure determine charge transport and mechanical behavior in conjugated polymer semiconductors.

My work uses multiscale structural and electrical characterization to connect molecular-level deformation with device-scale electronic performance.

I study organic semiconductors and organic field-effect transistors (OFETs) that retain electronic performance under mechanical deformation.

Research topics include strain-dependent structural evolution, charge transport, backbone flexibility, crosslinking strategies, and interface engineering for deformable organic semiconductor devices.

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.
