• 1990–1995: Ph.D. in Physics, University of California, Santa Barbara

Work

Lee is currently a Full Professor of Materials Science & Engineering Department and a Vice-Director of Heeger Center for Advanced Materials at the Gwangju Institute of Science and Technology (GIST), Korea. His major areas of interest include polymer devices such as polymer LEDs, polymer solar cells, and polymer FETs using semiconducting and metallic polymers. He received BS degree from Seoul National University in 1983, and MS degree from KAIST in 1985. Then he worked at the Korea Atomic Energy Research Institute as a Staff Researcher for 1985–1990. He moved to the USA for his doctorate study in 1990 at the University of California, Santa Barbara (UCSB) and obtained his Ph.D. degree in March 1995 under the supervision of Professor Alan J. Heeger (Nobel Laureate in Chemistry in 2000). After finishing his post-doctoral work at UCSB during 1995–11997, he started his professorship at the Pusan National University in South Korea in 1997. In 2007, he moved to his current position as a Distinguished Professor of GIST.

Outstanding breakthroughs

• Established a theoretical model of charge dynamics in conducting polymers called the localization-modified Drude model.[1]
• Produced true metallic polymers.[2]
• Fabrication of all-solution processable tandem polymer solar cells[3]
• Internal quantum efficiencies approaching 100% were obtained in polymer solar cells.[4]
• The conductivity of conducting polymer films was increased by aligning polymer chains.[5]
• Electrostatically Self-Assembled Nonconjugated Polyelectrolytes as an Ideal Interfacial Layer for Inverted Polymer Solar Cells[6]
• Role of interchain coupling in the metallic state of conducting polymers[7]
