Spring constant calibration of atomic force microscope cantilevers of arbitrary shape.
The spring constant of an atomic force microscope cantilever is often needed for quantitative measurements. The calibration method of Sader et al. [Rev. Sci. Instrum. 70, 3967 (1999)] for a rectangular cantilever requires measurement of the resonant frequency and quality factor in fluid (typically air), and knowledge of its plan view dimensions. This intrinsically uses the hydrodynamic function...
متن کاملAn analytic model for accurate spring constant calibration of rectangular atomic force microscope cantilevers
Spring constant calibration of the atomic force microscope (AFM) cantilever is of fundamental importance for quantifying the force between the AFM cantilever tip and the sample. The calibration within the framework of thin plate theory undoubtedly has a higher accuracy and broader scope than that within the well-established beam theory. However, thin plate theory-based accurate analytic determi...
متن کاملCalibration of rectangular atomic force microscope cantilevers
A method to determine the spring constant of a rectangular atomic force microscope cantilever is proposed that relies solely on the measurement of the resonant frequency and quality factor of the cantilever in fluid ~typically air!, and knowledge of its plan view dimensions. This method gives very good accuracy and improves upon the previous formulation by Sader et al. @Rev. Sci. Instrum. 66, 3...
متن کاملNormal and torsional spring constants of atomic force microscope cantilevers
Two methods commonly used to measure the normal spring constants of atomic force microscope cantilevers are the added mass method of Cleveland et al. @J. P. Cleveland et al., Rev. Sci. Instrum. 64, 403 ~1993!#, and the unloaded resonance technique of Sader et al. @J. E. Sader, J. W. M. Chon, and P. Mulvaney, Rev. Sci. Instrum. 70, 3967 ~1999!#. The added mass method involves measuring the chang...
متن کاملCalibration of higher eigenmode spring constants of atomic force microscope cantilevers.
Standard spring constant calibration methods are compared when applied to higher eigenmodes of cantilevers used in dynamic atomic force microscopy (dAFM). Analysis shows that Sader's original method (Sader et al 1999 Rev. Sci. Instrum. 70 3967-9), which relies on a priori knowledge of the eigenmode shape, is poorly suited for the calibration of higher eigenmodes. On the other hand, the thermal ...
