Description
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.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
