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.
