AFM Scan Speed Phenomena



Jason P. Killgore, Christopher C. Glover, Ryan Tung


This work presents data confirming the existence of a scan speed related phenomenon in contact mode atomic force microscopy. Specifically, contact resonance spectroscopy is used to interrogate this phenomenon. A monotonic decrease in the recorded contact resonance frequencies is observed with increasing scan speed. A squeeze film hydrodynamic theory is proposed to explain this phenomenon.
