WebHow Intermittent-Contact AFM Works The underlying principles for intermittent-contact AFM are the same as those for noncontact AFM. The difference is that for IC-AFM the cantilever is driven (forced to vibrate) at a fixed frequency close to, but less than, its free-space resonant frequency, as shown in Figure below. WebThe AFM can be resupplied at starports and outposts from the munitions interface. The Auto Field-Maintenance Unit (AFMU) is a module that can be used to repair other modules. …

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 ... http://web.mit.edu/cortiz/www/3.052/3.052CourseReader/13_AFM.pdf eglin medical group fax number
