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 کاملMeasuring the spring constant of atomic force microscope cantilevers: thermal fluctuations and other methods
Knowledge of the interaction forces between surfaces gained using an atomic force microscope (AFM) is crucial in a variety of industrial and scientific applications and necessitates a precise knowledge of the cantilever spring constant. Many methods have been devised to experimentally determine the spring constants of AFM cantilevers. The thermal fluctuation method is elegant but requires a the...
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 کاملA method for determining the spring constant of cantilevers for atomic force microscopy
Cantilevers fabricated by means of micromachining techniques are usually used for atomic force microscopy. In this paper, the spring constant of an atomic force microscope (AFM) cantilever is determined by using a large-scale cantilever. Since the spring constant of the large-scale cantilever is calibrated accurately, the spring constant of the AFM cantilever is determined precisely by measurin...
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...
