While friction typically arises from direct mechanical contact between surfaces, energy dissipation can also occur even

The present modification can be experimentally evaluated by comparing the lateral force measured with the torsional oscillation mode and that from three

• ). The absence of the signal at the center of the cantilever can also serve as a signature to clearly identify a torsional oscillation mode. Performance of the SPM Relevant AFM noise sources Compared to tuning fork sensors, microfabricated low-mass cantilevers offer considerable advantages concerning
