Delaminating CVD graphene from its metal substrate by “bubbling”
BIOTEC, Seminar room E05/E06 , Tatzberg 47/49 , 01307 Dresden
Abstract: Graphene is a new wonder material. It is one layer of carbon atoms in hexagonal lattice. High quality graphene has the world’s highest electron mobility, thermal and electrical conductivity, flexibility, etc. It has high potential in future nanoelectronics. However, before we talk about any applications, we first need to synthesize graphene. Today the most electronic-industry compatible technology is CVD (chemical vapor deposition). But this is typically done on a metal substrate such as copper. How to nicely transfer the graphene from the metal substrate to the target substrate such as SiO2 for practical use? How to make the process of low cost and environmental friendly? This talk will introduce the experiment and theory on an interesting process of delaminating graphene from metals by “bubbling”. Some basic background knowledge of graphene will also be introduced, together with an overview into applications.
Prof. Jie Sun (Senior member of IEEE) was born in 1977. He holds two PhD degrees from Institute of Semiconductors, Chinese Academy of Sciences, and Solid State Physics Division, Lund University, Sweden. He has been a Postdoctoral Fellow, Assistant Professor and Associate Professor in Chalmers University of Technology, Sweden. He is also an Adjunct Professor in Beijing University of Technology, China. His major is semiconductor and carbon materials and devices. In particular, he focuses on III-V and Si semiconductors, high-k dielectrics, ballistic and quantum transport, and carbon electronics. Currently, he is responsible for CVD of graphene and its applications in Chalmers and Beijing University of Technology. He has published about 80 papers covered by Web of Science. He is the only teacher of the world’s first MOOC "Introduction to graphene science and technology" at edx.org.
This seminar will take place within BIOTEC lecture series on Nanoscience and Nanotechnology which is held in the framework of the Erasmus Mundus program offered by KU Leuven, Chalmers University of Technology Göteborg, Université Grenoble Alpes and TU Dresden.
Everybody is welcome!
