Abstract

This paper aims to develop an effective multiscale simulation technique for the deformation analysis of nanotube-based nanoswitches. In the multiscale simulation, the key material parameters, (e.g., Young's modulus and moment of inertia) are extracted from the MD simulation which can explore the atomic properties. Then, the switches are simplified to continuum structure which is discretized and simulated by the advanced RBF meshfree formulation. The system of equations is nonlinear because the nonlinear loading is calculated from coupled the electrostatic, the elastostatic, and the van der Waals energy domains. Besides the normal deformation analysis, the pull-in voltage characteristics of different nanoswitches based on the double-walled nanotubes are analyzed. Comparing with the results in the literature and from experiments, it has proven that the developed multiscale approach is accurate and efficient.

Citation countsare 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.
