Calibration of lateral force measurements in atomic force microscopy with a piezoresistive force sensor.
We present here a method to calibrate the lateral force in the atomic force microscope. This method makes use of an accurately calibrated force sensor composed of a tipless piezoresistive cantilever and corresponding signal amplifying and processing electronics. Two ways of force loading with different loading points were compared by scanning the top and side edges of the piezoresistive cantile...
متن کاملCalibration Weighting to Compensate for Extreme Values, Non-response and Non-coverage in Labor Force Survey
Frame imperfection, non-response and unequal selection probabilities always affect survey results. In order to compensate for the effects of these problems, Devill and Särndal (1992) introduced a family of estimators called calibration estimators. In these estimators we look for weights that have minimum distance with design weights based on a distance function and satisfy calibration equa...
متن کاملLateral force calibration in atomic force microscopy: A new lateral force calibration method and general guidelines for optimization
Proper force calibration is a critical step in atomic and lateral force microscopies (AFM/LFM). The recently published torsional Sader method [C. P. Green et al., Rev. Sci. Instrum. 75, 1988 (2004)] facilitates the calculation of torsional spring constants of rectangular AFM cantilevers by eliminating the need to obtain information or make assumptions regarding the cantilever's material propert...
متن کاملLateral force calibration of an atomic force microscope with a diamagnetic levitation spring system
A novel diamagnetic lateral force calibrator D-LFC has been developed to directly calibrate atomic force microscope AFM cantilever-tip or -bead assemblies. This enables an AFM to accurately measure the lateral forces encountered in friction or biomechanical-testing experiments at a small length scale. In the process of development, deformation characteristics of the AFM cantilever assemblies un...
