A multiphysics model for carbon nanotube based nanoelectromechanical contact switch

This research builds up a multiphysics molecular model for nano electromechanical contact switch in a gaseous environment. To predict the device dynamic properties precisely, multiple methods have been incorporated, including: grand canonical Monte Carlo method for adsorption phenomenon, atomistic moment theory for dynamic electric field, and molecular dynamic simulation for carbon nanotube deformation. Using such a model, the charge distribution has been characterized; the adsorption influence on the frequency change and damping ratio has been investigated. The model has a great potential in the future design of nano electromechanical system.
