Abstract:
A study of nanomechanical cantilevers vibrating at various resonating modes in liquid is presented. Resonant frequency spectrum with 16 well resolved flexural modes is obtained. The quality factor increased from 1 at mode 1 to 30 at mode 16. The theoretical estimate of eigenfrequency using the Elmer?Dreier model [ F.-J. Elmer and M. Dreier, J. Appl. Phys. 81, 12 (1997) ] and Sader?s extended viscous model [ C. A. Van Eysden and J. E. Sader, J. Appl. Phys. 101, 044908 (2007) ] matched well with the experimental data. The apparent mass of the liquid comoved by the oscillating cantilevers decreased asymptotically with mode number.
