I will give an
account of nanoelectromechanical resonators based on carbon nanotubes and
graphene, from a personal and historical perspective: what are we doing and why?
I will start by reviewing some of our
early theoretical work on CNT NEMS and discuss some of the possibilities and
challenges associated with it. I will present two solutions to the challenges
posed by the small signal levels in CNT NEMS, and discuss nanoelectromechanical
CNT transistors and graphene membranes. Much of the work I discuss falls in the
domain of applicable – if not already applied – physics, but I will conclude
with a brief exposition of the possibilities offered by graphene resonators in
the fundamental field of quantum nanoelectromechanics. The work described
in this presentation is covered in more detail in our publications in Nano Letters 8, 1224 (2008), Science 325, 1107 (2009), EPL 91, 48001 (2010), Nano Letters 11, 1439 (2011). Prof. Kinaret is the head of the Condensed
Matter Theory group at the Chalmers University of Technology in Gothenburg,
Sweden. He was born in 1962 in Finland, where he also obtained his M.Sc.
degrees in theoretical physics and electrical engineering before moving to MIT
where he graduated with a Ph.D. in Physics in 1992. In 1995 he moved to a
faculty position in Gothenburg, Sweden. His main research directions are
fundamental and applied NEMS based on carbon nanotubes and graphene,
nano-opto-electromechanics, and, most recently, graphene plasmonics. He is
presently director of Nanoscience and Nanotechnology at Chalmers and the
coordinator of an FET Flagship Pilot project that prepares for a large scale
European research flagship on graphene and related two-dimensional materials.
