Jari Kinaret: Nonlinear nanoelectromechanics with carbon

posted 11 Jul 2011, 02:18 by Peter Bøggild
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.
