Deformation characterization of a nanoelectromechanical switch

This paper analyses the deformation of a double-walled nanotube-based nanoelectromechanical switch. The product of Young's modulus and moment of inertia of the tube is determined by a molecular dynamics simulation with a linear deflection approximation. The switch is simplified to a beam system, and the loading is calculated from three coupled energy domains: the electrostatic energy domain, the elastostatic energy domain, and the van der Waals energy domain. A meshless formulation is then used to discretize the switch to establish the non-linear system of equations for analysis. A parametric comparison with the results in the literature showed that the method developed in this paper is very effective.
