TORSIONAL RESONANCE (TR)

In torsional resonance (TR) mode, the tip of the atomic force microscope (AFM) moves parallel (relative to perpendicular) relative to the surface. In order to maintain a constant distance between the probe and the surface of the test sample, a force that causes a beneficial change in resonance behavior is applied between the AFM probe and the sample. Finally, the changes in the torsion-related dynamic characteristics of the tip-cantilever system caused by the in-plane (lateral) tip-sample interaction are used for surface property imaging. The main benefit of TR mode is that the tip always maintains a constant distance from the surface. This is especially useful in TUNA or near-field optical experiments.
