Title: Introduction of nanoelectromechanical systems and simulation of graphene nanoswitches using molecular dynamics method Abstract: Reducing the dimensions of nano-switches is very important in terms of integration, but for some reasons, including empirical obstacles or theoretical complexity, nano-switches with small lengths have not been studied yet. In this study, the performance of graphene nano-switches with lengths of less than 30nm and very low plate spacing (about nm2) is simulated using a combination of molecular dynamics and method of moments. The obtained results are compared with some of the available theoretical models. The results show that by decreasing the length of the nano-ribbons or increasing distance between plates, the pull-in voltage of the nano-switches is increased. The results also show that in long nano-ribbons, there is a good agreement with theoretical results, but in the short ones, the existing theoretical relations are not sufficiently precise and cannot predict the pull-in voltage accurately. Furthermore, the results show that the switching times of the simulated nano-switches are considerably less than conventional nanoswitches.
