Short Biography

  Dr. Jong Kyu Kim is an associate professor at the Department of Materials Science and Engineering in POSTECH. After he received his Ph. D. degree from POSTECH in 2002, he joined the Future Chips Constellation at Rensselaer Polytechnic Institute as a research assistant professor. Dr. Kim has made pioneering contributions to the field of compound semiconductor materials and devices in particular to the fields of AlGaInN-based light-emitting diodes (LEDs) and future smart lighting applications. His recent research topics include 3-Dimensional nano-structured materials for nano-photonics applications such as near-perfect antireflection coatings for photovoltaic cells, nanostructured electrodes for organic photovoltaics, water splitting electrochemical cells, electronics noses, and dye-sensitized solar cells.

  He has authored or co-authored more than 140 peer-reviewed publications including recent publications in Nano letters, Nature Photonics, Science, and Advanced Materials, and 4 book chapters. His papers have been cited more than 7000 times (average citations per paper >47) and h-index is 40 until now (June 2016). His research on near-perfect anti-reflection coating in collaboration with his colleagues was selected as " The 25 most innovative nano/micro technologies 2007" by R&D magazine. He is a member of Materials Research Society (MRS), The Minerals, Metals & Materials Society (TMS), and The International Society for Optical Engineering (SPIE).
