Multi-function analytical facility for surface science in Hong Kong

Surface properties of semiconducting materials have important influences on their applications for a wide spectrum of optoelectronic devices. With over 20-year experience on surface analysis using advanced analytical spectroscopies and ultrahigh vacuum instruments design, Professor Lee Chun-sing, Head of the Department of Chemistry and Director of the Centre of Super-Diamond and Advanced Films of City University of Hong Kong (CityU), leads a team with members comprising CityU, The Chinese University of Hong Kong, Hong Kong Baptist University, The University of Hong Kong, Hong Kong University of Science and Technology and The Hong Kong Polytechnic University, won a CRF project of over HK$ 5.7 million to build a “Multi-function Analytical Facility with Time-resolved Two-photon Photoemission (TR-2PPE) Spectroscopy”.

Professor Lee and his team believe that this analytical facility will be a powerful tool to provide essential support for revealing surface energetics, chemical/ elemental studies, and advance charge energetics/ kinetics for both occupied and unoccupied state electrons, which cannot be obtained with any existing systems in Hong Kong. With this new facility, the team aims to equip Hong Kong’s researchers with an up-to-date and versatile tool for studying charge dynamics as well as electronic and chemical properties of different semiconducting materials.
