报告摘要：  

Graphene nanomechanical resonators are the thinnest vibrating membranes imaginable, and as such they play an important role in the study of the dynamics of flexural vibrations in two-dimensional systems. This presentation will address two separate research works about graphene resonators that are ongoing in my lab.The first work addresses the problem of graphene resonators with unconventional boundary conditions. The second work is about a simple data acquisition system we developed that allows us to perform a variety of nanomechanical measurements using a single platform.

个人介绍：

Joel Moser graduated from Paris University in France in October 1999. The topic of his PhD research was high-pressure physics, with an emphasis on the transport properties of low-dimensional organic conductors. After graduation he branched out and developed an interest in nanofabrication and quantum transport, two topics he worked on as a postdoc in the US (Boston College and Harvard Medical School) and in Germany (Technical University in Munich). In 2007 he joined Adrian Bachtold’s group in Barcelona, Spain, as a research fellow. There, he worked on charge transport and nanomechanics in nanotubes and graphene. Since October 2015, he has been a professor at the School of Optoelectronic Science and Engineering at Soochow University in Suzhou, China. His group works on low-dimensional nanomechanical resonators using optics and radio frequency electronics. Their goal is to realize new hybrid states in low-dimensional resonators whereby flexural vibrations and electronic phases are coupled.
