摘要: Double-layer graphene sheets (DLGSs) have potential applications as nanoelectromechanical systems (NEMS) resonators due to their specific carrier spectrum of electrons. In this study, analysis the vibration modes NEMS using simply supported circular DLGSs has been undertaken based on nonlocal thin plate theory. Considering properties DLGSs, mode can be divided into an in-phase (IPM) and anti-phase (APM). The range resonance frequencies in IPM is much larger than APM because influence van der Waals forces. Nonlocal effects significantly frequency higher at lower aspect ratios.
