摘要：

The resonators based on graphene nanoribbon have been of interest for a building block to develop electro-mechanical devices on a nanometer scale. Here, we present resonator schematics based on a cross-type graphene and investigate its dynamic features via classical molecular dynamics simulations. This cross-type graphene-resonator can detect the tension and electrical variations in two-dimension. Our simulation results showed that the cross-type graphene-resonator exhibits great potential in the applications to detect the polarization of the zigzag or armchair directions, because its oscillation dynamics are electromechanically coupled and its electronic states directionally depend on the edge structures by controlling the widths of the zigzag and the armchair edges. The deflective motions of the cross-type graphene-resonator under the driving forces were very similar to those of the graphene-nanoribbon resonator. (C) 2013 Elsevier B.V. All rights reserved.
