Dr. Xu received his B.Sc. and M.Sc. from Nanjing University in 1983 and 1986, respectively, in Physics and Information Physics, under the supervision of Prof. Shu-yi Zhang (Member of Chinese Academy of Sciences). Since 1988, he was highly privileged to study in the University of Konstanz (an elite university), particularly under the supervision of Prof. Klaus Dransfeld (Member of German Academy of Sciences, former Director of Max-Plank Institute for Solid State Research, and Max-Plank Institute for High-Magnetic Fields). His doctoral dissertation was focused on the near-field sensing and nanoscopic energy transfer and heat transport associated with electronic processes. He earned his doctorate (Dr. rer. nat.) in 1993. Afterwards, he joined the Department of Electronic Engineering, The Chinese University of Hong Kong. He has been Professor in the department since the midst of 2002.
Dr. Xu has published extensively on advanced electronic and photonic materials and devices as well as on nanotechnology in peer-reviewed professional journals (c.a. 240) and conferences (c.a. 50) as well as more than 200 presentations, including conference invited talks, colloquia, seminars, etc. The published papers have been extensively accessed and cited, as well as many topic reviews and monographs, and patents. Meanwhile, he has secured numerous competitive research grants. Also he actively participates in a myriad of professional activities and has served as symposium chair in several international conferences. Particularly, he has served as Member of International Advisory Committee, International Conference on Nanoscience and Technology, China 2009 (ChinaNano 2009), and as Director of Advanced Study Institute on Printed Electronics 2013 (Dedicated to Professor Sir Charles Kao on the Occasion of his 80th Birthday). He is Fellow of Hong Kong Institution of Engineers, Senior Member of IEEE, the Secretary and Council Member of Hong Kong Materials Research Society, and Member of American Physical Society, Materials Research Society, Hong Kong Institution of Science, and Physical Society of Hong Kong. Since 2007, he has been Director of Materials Science and Technology Research Center in CUHK. From 2011, he has been Convener of Strategic Initiatives for Nano, Energy, and Materials in CUHK.
