Force modulation mode

WebThe NC AFM works via the principle “amplitude modulation” detection. The corresponding detection scheme exploits the change in the amplitude, A, of the oscillation of a cantilever due to the interaction of a tip with a sample. To the first order, the working of the NC AFM can be understood in terms of a force-gradient model [1]. WebThe CoreAFM can perform static force, dynamic force, phase imaging, MFM, lateral force, force modulation, standard spectroscopy, and standard lithography out of the box. You can however enhance your measurement experience with CoreAFM mode kits.
