Single-Electron Transport in Nano-Electromechanical Devices — •Yaroslav M. Blanter — Kavli Institute of NanoScience, Delft University of Technology, 2628 CJ Delft, The Netherlands

We first review existing experimental and theoretical developments in nanoelectromechanical systems (NEMS) in the single-tunneling regime. Next, we discuss effect of electric degrees of freedom on the mechanical properties and show that eigenfrequencies of suspended beams can be tuned by the gate voltage (as confirmed recently by the Cornell group). Then, we consider the situation of a strong mechanical feedback and discuss the modification of transport properties by mechanical motion.
