WebAFM feedback, based on the tuning fork oscillations, can be used to maintain a constant tip-sample distance using the tuning fork's amplitude, phase, or frequency. STM probes operated in this mode still benefit from the laser-free feedback and a very stiff spring constant that avoids jump to contact instabilities, as described above for ... WebAtomic Force Microscopy (AFM) is a high-resolution non-optical imaging technique first demonstrated by Binnig, Quate and Gerber in 1985 [1].
