Abstract

By means of force spectroscopy measurements performed with the cantilever first and second flexural modes under the frequency modulation detection method, the authors corroborate the validity of the relation between tip-surface interaction force and frequency shift for force spectroscopy acquisition using higher cantilever eigenmodes. They est. a cantilever effective stiffness for the second eigenmode 73 times larger than the static stiffness. This large effective stiffness enables them to perform force spectroscopy with a cantilever oscillation amplitude (A0) as small as 3.6 A. The authors provide exptl. evidence that, at such small A0 values, normalized frequency shift curves deviate from a A03/2 scaling and the signal-to-noise ratio is considerably enhanced.
