Design and Modeling of Carbon Nanotube Electromechanical Switches for Logic Device Application
Abstract:Nanoelectromechanical switches consisting of carbon nanotubes suspended over metal electrodes are presented and their electromechanical responses are investigated. The device operates as transistors with the suspended part of the nanotube bent to touch metal electrodes via electrostatic force by applying voltage. The device is modeled using multiphysics simulation. Assuming continuum mechanics the nonlinear deformation of the nanotube is simulated using reduced order method. In particular, singly and doubly clamped nanotubes under electrostatic actuation are investigated and the pull-in voltage of the device, a key design parameter, are predicted and emphasized. These models provide a guide on the effect of the various geometrical variables and insight into the design of nanoswitches for logic device application.
