摘要：
二维（2D）层状过渡金属硫属化合物（TMDs）材料具有独特的光电特性，是研制未来新型光电器件的基础之一。通过CVD方法实现了几种二维材料的制备，以及研究相关器件的界面工程。通过显著地减少界面活性区域中的电学缺陷及相关过程，同时利用层状材料/光子学结构混合体的电磁相互作用，我们能够实现从可见光到红外光谱区域以及太赫兹波段的几种高性能光电子器件。
Two dimensional materials (TMDs) possess unique photoelectric properties, as one of foundations to develop future novel photoelectric devices. By chemical vapor deposition (CVD), it can synthesize some kinds of 2D materials, and the interfacial engineering of these 2D materials-based device is investigated. To achieve several high performance photoelectric devices with the response from visible to terahertz, we distinctly reduce the electrical defect and correlated process in interfacial active zone, and utilize 2D materials-photonic crystal integration to realize high electromagnetic interaction.

Dr. Xu received his B.Sc. and M.Sc. from Nanjing University in 1983 and 1986, respectively, in Physics and Electronic Science and Engineering, 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, and IEEE Fellow. Dr. Xu is also professor of the Yangtze river scholar of education (physical electronics) and 1,000 Talents Plan/Thousand Talents Program. He works on nano-Science and Technology, Solid electronics physics and materials, and Semiconductor physics of optoelectronic device. He has also obtained many innovative achievements, including in characterizations of Nanometer scale, Nano heat conduction, MOS gate dielectric, Physics of organic semiconductor device interface, Graphene or 2D materials devices and physics, and Perovskite solar cells, which have an important impact on international peers.
