Summary

Ji-Seon Kim is Professor of Solid State Physics, Director of the EPSRC Plastic Electronics Centre for Doctoral Training (http://www.imperial.ac.uk/plastic-electronics-cdt/) and MRes in Soft Electronic Materials at Imperial College London. She also holds a Specially Appointed Professorship at Tokyo Institute of Technology (Japan), and held a WCU Professorship at KAIST (South Korea). She has previously taken up an EPSRC Advanced Research Fellowship at the University of Cambridge, obtained a PhD in Physics in 2000 under the supervision of Prof. Sir Richard Friend.

Kim's group research focuses on the molecular physics of sustainable organic and hybrid electronic materials. It addresses basic science and technology challenges for molecular semiconductors, extending it towards New Electronic Materials including organic/inorganic hybrids and bio-nanomaterials, exploring fundamental scientific issues related to using these materials for novel optoelectronic applications. It also parallels with developing Advanced Nanometrology for these materials. Two main research themes in her group are (a) to facilitate the rational design of nanoscale electronic materials for electronic applications by providing in-depth understanding and control of their nanostructures and optoelectronic properties; (b) to develop advanced spectroscopy techniques that have the unique capability to probe nanoscale non-periodic structures and energetics at organic and hybrid interfaces. Experimental work is accompanied by theoretical simulation. The success of her program is based on strong collaborative endeavour ranging from materials synthesis/ processing, physical/ electrical characterisation and device fabrication/ modelling, which includes strong collaborations with various national/ international universities and industrial partners. The current research programme is focused on organic and perovskite solar cells, alongside organic bioelectronic and biosensor devices with dual electronic and ionic functionality.

She is leading the Nanoanalysis Group (http://www.imperial.ac.uk/nanoanalysis-group), working together with industrial partners including Samsung Electronics, CSEM Brazil, KP-Tech, CDT Ltd. and NPL.
