Abstract
Timoshenko beam model is employed to investigate the vibration of atomic force microscope (AFM) cantilevers in contact resonance force microscopy (CRFM). Characteristic equation with both vertical and lateral tip-sample contact is derived. The contact resonance frequencies (CRFs) obtained by the Timoshenko model are compared with those by the Euler−Bernoulli model. A method is proposed to correct the wave number obtained by the Euler−Bernoulli model. The forced vibration is compared between the two models. Results reveal that the Timoshenko model is superior to the Euler−Bernoulli model in predicting the vibration characteristics for cantilevers’ higher eigenmodes.
