Shaping Thin Solid Films into Functional and Integrative Nanomembranes

Recently, tremendous attention has been directed toward the thinning and shaping of solids into so-called nanomembranes, offering a unique and fantastic platform for research in nanoscience and nanotechnology. In this talk, a conceptual description of nanomembranes is introduced and a series of examples demonstrate their great potential for future applications. The thinning of nanomembranes indeed offers another strategy to fabricate nanomaterials, which can be integrated onto a chip and exhibit interesting properties. Furthermore, the stretching of nanomembranes enables a macroscale route for tuning the physical properties of the membranes at the nanoscale. The process by which nanomembranes release from a substrate presents several approaches to shaping nanomembranes into three-dimensional architectures, such as rolled-up tubes, wrinkles, and the resulting channels, which can provide fascinating applications in electronics, mechanics, fluidics, and photonics. Nanomembranes as a new type of nanomaterial promise to be an attractive direction for nano-research as well as for flexible electronics.
Yongfeng Mei received his BS and MS in physics from Nanjing University (China) and PhD in physics and materials science from City University of Hong Kong.  He is a full professor in materials chemistry and physics in the Department of Materials Science in Fudan University.  Before that, he worked as a post-doctoral researcher in the Max Planck Institute for Solid State Research (Germany) and then led a research group in the Leibniz Institute for Solid State and Materials Research Dresden (Germany).  His research interest focuses on the development of novel inorganic nanomembranes and their properties in optics, optoelectronics and micro-/nanoscale mechanics. He has published more than 130 journal papers and H-index 30. He also serves as guest editors for Nanoscale Research Letters and Nanotechnology, and has chaired several international conferences.
