Nano system operates with interacting electrons, but no electric current

(Phys.org)—Illustrating the unusual way things work on the nanoscale, scientists have designed a new nanoelectromechanical system (NEMS) that produces mechanical motion due to the interactions between electrons—yet unlike similar systems, this system does not require any electric current. Instead, the electron-electron interactions couple two electron reservoirs of different temperatures, which generates a heat flow between them that causes a suspended carbon nanotube to vibrate.
