1. Sader Method for a set of rectangular/non-rectangular cantilevers.
2. Sader Method GCI for all cantilever types.

Mathematica Files

These Mathematica ® notebooks and script files have been made available to assist in the calibration of AFM cantilevers using the Sader methods. In addition, we have also made available a notebook that fits the thermal noise spectrum of an AFM cantilever with the response of a simple harmonic oscillator (the file SHOfit.nb). This can be used to extract the peak frequency and quality factors of the resonance peaks to high accuracy (± 0.1% and ± 1%, respectively).
