A Nanoscale Electromechanical Contact Switch for Logic Applications

摘要

Here, we describe the operation of a nano-electro-mechanical contact switch. The switch design relies on a sharp contact tip integrated to a compliant nanomechanical beam. When the beam is actuated electrostatically, the tip establishes intimate electrical contact between two electrodes. A preliminary contact switch was fabricated on a Si_3N_4 membrane using optical lithography, electron beam lithography and reactive ion etching. Its quasi-static operation was subsequently demonstrated.
