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 EulerâBernoulli model. A method is proposed to correct the wave number obtained by the EulerâBernoulli model. The forced vibration is compared between the two models. Results reveal that the Timoshenko model is superior to the EulerâBernoulli model in predicting the vibration characteristics for cantilevers' higher eigenmodes.
