TLDR
In this paper, an approximate analytical expression of the critical pull-in gap with Casimir force is presented by the perturbation theory, from which one can notice the nonlinear effect of Casimir forces on the pullin parameters.Abstract:
Casimir effect on the critical pull-in gap and pull-in voltage of nanoelectromechanical switches is studied. An approximate analytical expression of the critical pull-in gap with Casimir force is presented by the perturbation theory. The corresponding pull-in parameters are computed numerically, from which one can notice the nonlinear effect of Casimir force on the pull-in parameters. The detachment length has been presented, which increases with increasing thickness of the beam.read more
