Summary:
A numerical study on force sensitivity of dynamic force microscopy is carried out near perioddoubling bifurcation of microcantilever vibration. A small periodic signal is additionally given to the driving signal of the microcantilever to utilize sensitive dependence of vibration on tip-sample distance. The additional periodic signal proposed here readily achieves the same effects as parametric excitation which has been employed for enhancing sensitivity.
