Molecular dynamics simulation on crossroad-type graphene-resonator accelerometer

Highly sensitive accelerometers have multiple applications in industry and science, and can be used as sensors in a wide variety of devices. Here, we investigate the application of crossroadtype graphene resonators as ultrahigh sensitivity accelerometers by performing classical molecular dynamics simulations. The relationships between the resonance frequencies and acceleration could be divided by two regions. The simulation data showed that when the accelerations were higher than 0.1 nm/ps2, the resonance frequency increased with increase of the acceleration. In particular, acceleration, as a function of frequency, was regressed by a power function and shown to have a linear relationship on a log-log scale. Crossroad-type graphene resonators have multiple applications to nanoscale sensors, filters, switching devices, and quantum computing, as well as ultra-fast response resonators. © 2015 American Scientific Publishers.
