### Biosketch

Dr. Lim has an extensive experience working in universities, companies, and research institutes in England, Japan, Singapore, Taiwan R.O.C., South Korea, Norway, and Vietnam. The organizations he worked for include the University of Leeds, The Furukawa Electric Company, Agilent Technologies, Institute for Infocomm Research, National Chiao Tung University, Advanced Industrial Science and Technology, Nagoya University, Sungkyunkwan University, and the Norwegian University of Science and Technology. He mainly works on photonic and photovoltaic device research, and has contributed to the development of semiconductor optical devices such as semiconductor lasers, quantum-confined Stark effect electro-absorption modulators, ultrafast all-optical cross-phase modulator, and radial p-n junction core-shell nanowire array solar cells; some of which are protected by intellectual property rights. He has a broad interest in photonics, photovoltaics, optoelectronics, electronics, and renewable energy; though his main passion is to investigate the fundamental physics of advanced nanostructures as well as optical and electronic properties of advanced novel materials, for developing advanced photonic, photovoltaic, optoelectronic, and electronic devices. At present, some of the topics that he is particularly interested in are on-chip optical devices, silicon photonics, compound semiconductor photonic devices, perovskite solar cells, hot-carrier solar cells, thermophotovoltaic cells, multi-junction solar cells, bifacial solar cells, graphitic and hybrid graphitic devices, plasmonics, hydrogen fuel-cell, energy storage, as well as optical coherence tomography. He warmly welcomes industrial and academic individuals, as well as students who are interested in any of the above research or related research to contact him.
