Nano-Mechanical Single-Electron Devices — •Alex Croy and Alex Eisfeld — MPI-PKS Dresden

The fabrication and utilization of nanoscale machines and devices is one of the great promises of the 21st century. In particular, so-called nanoelectromechanical systems provide intriguing possibilities for applications beyond common paradigms. The involvement of mechanical parts promises increased robustness, low power-consumption and higher operating temperature compared to conventional devices. One paradigm in this regard is the nanomechanical single-electron transistor (NEMSET) proposed by Gorelik et al. which can exhibit mechanically assisted charge transport.

In this context, we present theoretical results for two new nanomechanical single-electron devices, which promise interesting applications. The first device consists of two couples NEMSETs and can be used for storage of information. The second device is a single-electron rotor, which generalizes the NEMSET concept and can act as a charge pump.
