Study of Electrostatic and Dispersion Forces in Nanoelectromechanical Systems (NEMS)

This chapter derived in brief the well-known relations of electrostatic and dispersion forces for beam-based nanostructures. The cases were classified for different structural configurations, i.e. rectangular beam–plate, wire–plate, cylinder–plate, carbon nanotubes-sheets, rectangular tweezers, circular tweezers, and CNT tweezers. In addition, the effects of different electric fringing field corrections, the freestanding phenomenon owing to the Casimir or van der Waals attractions, and other famous theories related to the Casimir force were studied separately. Due to the lack of similar classified relations in the literature, they have been expected to contribute to the development of the nanotechnology and would be beneficial to the modeling of actuated nanodevices.
