▎ 摘　　要

We present the simple schematics of the double-gate graphene-nanoribbon (GNR)-based nano-electromechanical relay and the model schematic of its fabrication processes, and investigated their operation dynamics via classical molecular dynamics simulations. The key operations of the proposed GNR relay are based on the low mass density, the large area, and the flexible deflection of the GNR. The electromechanical dynamics of the GNR-relay are well understood by five forces such as the capacitive force between the top electrode and the GNR, the van der Weals force between the top electrode and the GNR, the capacitive force between the bottom electrode and the GNR, the van der Waals force between the bottom electrode and the GNR, and the elastic force of the GNR. The switching speed of the GNR-relay decreases by increasing the electrostatic force. We anticipate the realization of this proposed GNR-based nano-electromechanical rely in further experimental works.
