主讲人:徐志平   清华大学工程力学系

个人简介:徐志平博士2002年和2007年于清华大学获得学士和博士学位,此后分别在2007-2008年和2008-2010年间分别在美国Rice大学和麻省理工学院从事博士后研究工作,2010年起在清华大学航天航空学院工作,现任工程力学系教授,主要研究兴趣为复杂微结构材料与系统的力学与动力学行为。

 

讲座内容:

Two-dimensional (2D) materials have been envisioned as wonder materials not only because of their fantastic properties, but also due to their unique role as model materials for fundamental research of 2D physics. In this talk, I will present the topological and geometrical effects of defects in modulating the structures and mechanical responses of 2D materials. We conclude that as the dimension is reduced, imperfections become vital for the material behaviors compared to those in the bulk. These effects have further implications in modulating the growth and assembly of graphene single-crystal domains into continuum films. The constructive aspect of defects in engineering 2D materials with designed pre-stress and geometry will also be discussed.
