Accuracy of these force measurements is important for quantitative nanomechanical measurements. Here we demonstrate a method to convert the torsional deflection signals into a calibrated force waveform with the use of non-linear dynamical response of the tapping cantilever. Specifically the transitions between steady oscillation regimes are used to calibrate the torsional deflection signals.13 pagesInstrumentation and DetectorsHarnessing bifurcations in tapping-mode atomic force microscopy to calibrate time-varying tip-sample force measurementstext
