Figure 4From: Surface roughness effects on the frequency tuning performance of a nanoelectromechanical resonatorElectrothermal damping effects on a nanoelectromechanical resonator. (a) Tuning ratio from the original resonance frequency in terms of the tuning voltage. (b) Actual tuned frequency based on the tuning power. (c) The variation of the resonance frequency resulting from tuning the voltage.Back to article page
