Force-Distance Spectroscopy

Force Measurement of Tip-Sample Interaction

Force-Distance (Fd) curves is a spectroscopy technique measuring the vertical interaction between the tip and the sample surface while extending and retracting a Z scanner. Function of a cantilever deflection versus the extension of the piezoelectric scanner is he direct measurement of tip-sample interaction forces reflecting a mechanical property of surface.
