Abstract
To have confidence in force measurements made with atomic force microscopes (AFMs), the spring constant of the AFM cantilevers should be known with good precision and accuracy, topics not yet thoroughly treated in the literature. In this study, we compared the stiffnesses of uncoated tipless uniform retangular silicon cantilevers among thermal, loading, and geometric calibration methods; loading was done against an SI-traceable artifact from NIST. The precision and accuracy of the thermal method were found to be 5 and 10% respectively. Force measurements taken with different cantilevers can now be meaningfully compared.Citation
