Deflection error afm
WebDynamic force mode refers to a collection of AFM modes in which the cantilever oscillates at a high frequency at or close to resonance. A specific kind of dynamic mode, referred to as amplitude modulation mode (AM-AFM) is the most common AFM imaging mode. In AM-AFM, the amplitude of oscillation is the feedback parameter; other dynamic modes ... WebApr 15, 2014 · Step 2 Calibrate Deflection Sensitivity.

Webdeflection ofthe cantilever, which indicates the local sample height. Thus, in contact mode the AFM measures hard-sphere repulsion forces between the tip and sample. In noncontact mode, the AFM derives topographic images from measurements of attractive forces; the tip does not touch the sample (Albrecht et aI., 1991). Because it does WebBelow is a short list of the most important steps for performing a successful AFM measurement on a system with optical AFM cantilever deflection detection.
