Nano-switch structure is an important control element in nano-electromechanical systems.Based on the surface energy model,the effects of surface effects and intermolecular forces on the linear bending behavior of nano-switch structures are analyzed respectively.Through the principle of minimum potential energy,the governing equation and boundary conditions of nanometer switch are derived,and the homo-to-py perturbation method is used to solve the nonlinear differential equation.The effects of surface effect on the bending deformation and the voltage of nano-switch under the influence of Casimir and surface effect are analyzed.The results show that the surface effects reduce the deformation of the nano-switch structure,thus increasing the absorption voltage,and the surface effect has a significant impact on the stability of the nano-switch absorption.It is of great theoretical significance and practical value for understanding and studying the mechanical behavior of nano-switch,as well as the design and preparation of nano-switch.
