  内容简介:

  Graphene belongs to a family of two-dimensional materials showing very intriguing electronic, optical, thermal, and mechanical attributes. Huge progress has been gained in the past decade or so, which shed promising light on the probable applications from visible to terahertz (THz) light waves. In order to advance the performance of graphene-based optoelectronic devices by capitalizing on the length of light-matter interaction beyond nanometer constraint, we investigate several routes towards high-performance optoelectronic devices (namely, photodetectors from visible to the near- and mid-infrared spectral regions, and THz modulators and sensors), by employing the unique electronic and optical properties of graphene and its intrinsic transition characteristics as well as specially designed device configurations. We greatly envision that the similar strategies are applicable to other two-dimensional transition metal dichalcogenides (TMDs) and the related heterostructures.

  主讲人简介:

  电子论坛第64期主讲人.pngDr. Jianbin Xu received the B.Sc. and M.Sc. degrees in physics and information physics from Nanjing University, Nanjing, China, in 1983 and 1986, respectively, and the Doctor of Natural Science in 1993, from the University of Konstanz, Konstanz, Germany, where he studied under the supervision of Prof. Klaus Dransfeld. His doctoral dissertation was focused on the near-field sensing and nanoscopic energy transfer and heat transport associated with electronic processes. Afterward, he joined the Department of Electronic Engineering, The Chinese University of Hong Kong, where he has been a Professor in the Department of Electronic Engineering since mid-2002. His research interests include advanced electronic and photonic materials and devices as well as nanotechnology. 

  Prof. Xu is a Fellow of IEEE and The Hong Kong Institution of Engineers; the Secretary and Council Member of the Hong Kong Materials Research Society; a member of the American Physical Society, the Hong Kong Institution of Science, and the Physical Society of Hong Kong; Associate Editor of Science Bulletin. Also he is a Distinguished Research Fellow at Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences.
