Prof. Sungsik LEE (Steven Sungsik Lee) is the director of the LEE Laboratory at the Department of Electronics Engineering, Pusan National University. Previously, he was a Research Associate at the Department of Engineering, University of Cambridge. He received the Ph.D degree from the University College London (UCL) in August 2013, where he investigated on semiconducting oxide thin-film transistors, after his enrollment in Sept. 2010. Before his Ph.D, he worked for one of the Korean national labs, ETRI, soon after the completion of his Master degree at KAIST. His research currently lies in the ‘Low Energy Electronics (LEE) and Related Device Research’ for Futuristic Electronics. Here, ‘Almost-off transistors‘ realized with thin-film technologies are mainly being studied because they are naturally & fundamentally super energy-efficient, and also perfect for low cost and large area systems associated with a thin-film technology’s advantage, such as wearable sensor systems in the IoT, where ultra-low power consumption is essential without a concern of speed (see his recent Science paper, press release: Many News Media and Korean News). Besides, he is also interested in totally new electronic devices, the Trancitor, rather than transistors as transfer-resistors, in order to make a more fundamental breakthrough in the area of electronic devices science-magazine-logoin a much longer term. In his area, he has published over 70 articles including SCI journals, invited/ contributed talks (e.g. 2 IEDM & 1 SID talks), and U.S. patents (see Publication).

Personal Aspects:

  • English nickname: Steven (can be ‘Steven Sungsik Lee’ as the full name in UK).
  • He is a descendant of Hwang Yi (퇴계 이황, 진성 이씨) who is one of the greatest philosophers of Korea.
  • He got married Mrs Soyun (Amy) Kim, who is a blogger and book author.
  • His elder brother, Kyungsik Lee is a professor at Seoul National University (SNU).
  • He really likes playing billiards (>150), singing songs (professional as a contest winner), and having a good time with alcohols although not so strong to it (> 1 bottle of soju and wine, but beers are not preferred).
  • He learned alcohols largely from his former supervisor, Prof. Arokia Nathan, at Cambridge, having a lot of frequent discussions in the local pub called ‘Beefeater‘, where they found the special scientific table #4.

Academic and Scientific Aspects:

  • Tenure-track Professorship at PNU* (Pusan National University) since 2017.

    UCL at UK

    *Note that the PNU is one of 10 Flagship Korean National Universities, and the 2nd best after the SNU.

  • RA (Cambridge), PhD (UCL), MS (KAIST), BS (KNU) in Electrical and Electronic Engineering (EEE).
  • Research Area of Expertise: Semiconductor Physics and Devices for Futuristic Electronics:
    1. General semiconductor devices and physics (MOSFET, TFT)
    2. Low power / low energy electronic devices (Almost-off Schottky barrier FET)
    3. Thin-film material physics and condensed matter physics (Organics / Inorganics)
    4. Neuromorphic devices (Synaptic transistors, Axon devices / circuits)
    5. Novel semiconductor devices and circuits (Trancitors, document in PDF)
  • International Collaborators: see the section ‘Collaborators‘.
  • Research Philosophy:
    1. Improve an Existing for Local Breakthrough: by Making a worse thing better in a certain principle or condition (i.e. breaking a trade-off relation), or Finding a new venue and principle even with a well-known thing.
    2. Create a Never Existed Before for Fundamental Breakthrough: by Creating a totally new drawing style although it is not so beautiful – it’s ok if this is for the first time, rather than Making an existing picture slightly more beautiful.
  • Study Philosophy: Our proposed “Study Philosophy” is described with the statement that “If you can explain a difficult terminology with common sense, now you understand it“. This is a definition of Genius whereas foolish people explain even an easy thing in a difficult way. So, you got to try to use an easy way of explaining even for a difficult matter. Then, you even can explain anything to anyone who is a non-expert, such as your grandmom.
