Welcome to Thin-Film Semiconductor Device Laboratory

We research on thin-film semiconductor based optoelectronic devices such as organic light-emitting diodes, quantum-dot light-emitting diodes, photovoltaic cells and thin-film transistors


Open positions for graduate students

We are looking for graduated students.

If you are interested in our laboratory, feel free to email me at any time. (Email: hnlee@sch.ac.kr)

In addition, it is highly recommended for foreign students to apply to GKS program for scholarship. (https://www.studyinkorea.go.kr/en/main.do)
