摘要: A switchable carbon-nanotube-based nanoelectromechanical systems (NEMS) with close-loop feedback is examined. The device consists of a cantilever carbon nanotube clamped to top electrode and actuated by bottom electrode. actuation circuit includes source resistor. pull-in/pull-out tunneling characteristics the system are investigated means an electromechanical analysis. model concentration electrical charge, at end nanocantilever, van der Waals force. analysis shows that has two well-defined stable equilibrium positions as result incorporation resistor circuit. Potential applications include NEMS switches, random-access memory elements, logic devices, electron counters, gap sensing devices.
