The field of molecular semiconductors has developed rapidly from fundamental laboratory discovery into a significant materials and manufacturing technology for a range of thin-film electronics applications including displays, solar cells, transistors and sensors. While innovation in new materials and processing techniques continues to improve the performance of organic devices, further research is required to gain crucial insights into the fundamental relationships between structure and property, and hence to inform future design strategies. In this talk, I will discuss the key advances on our understanding of molecular semiconductors in terms of their molecular physics critical for energy and healthcare materials.
I will introduce our recent work focusing on molecular vibrational spectroscopy to identify chemical structure, molecular conformation, orientation, and their impact on fundamental photo- and electro-chemical processes. I will highlight how these properties influence the optoelectronic processes related to generation, extraction, trapping, and recombination of charge carriers critical to the performance of solar cell and biosensor devices.
Ji-Seon Kim is Professor of Solid State Physics and Director of the Plastic Electronics Centre for Doctoral Training (https://www.imperial.ac.uk/plastic-electronics/) at Imperial College London. She also held a Visiting Professorship in Materials Science and Engineering 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. She is conducting scientific research as a technical consultant for Cambridge Display Technology Ltd.
Her research focuses on the basic science and technology of Soft Electronic Materials for Energy and Bio applications, as well as developing new Nanometrology for these materials. Her research programme benefits from multidisciplinary scientific background in theoretical and experimental physics and surface/interface science, which provides a unique perspective to approach the research programme in molecular, polymeric, and hybrid electronic materials and devices. She is leading the Nanoanalysis Group (http://www.imperial.ac.uk/nanoanalysis-group).
