Nanoelectromechanical system oscillators have been proposed for a variety of applications, such as radio-frequency signal processing and ultrasensitive sensing. Carbon nanotube (CNT) oscillators demonstrated that the resonance frequency can be widely tuned and the motions can be self-detected. The resonant behaviours of two types of CNT oscillators with cantilevered and fixed–fixed CNT resonators are investigated by continuum mechanics-based multiphysics finite-element method simulations using a reduced order model. It is found that these two types of devices have different resonant responses when the DC bias changes: the resonant frequency of fixed–fixed CNTs increases as the DC bias increases, whereas the resonant frequency of cantilevered CNT devices decreases as the DC bias increases. The simulations also show that the fixed–fixed CNT oscillators have better tuning capabilities than the cantilevered CNT devices. Therefore in general fixed–fixed CNTs should be used in the oscillator designs, unless the unique resonant behaviour of the cantilevered devices is desired.
