Effect of material stiffness on intermodulation response in dynamic atomic force microscopy
2010 (English)In: ASME 2010 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, New York: Amer Soc Mechanical Engineers , 2010, 499-506 p.Conference paper (Refereed)
We perform simulations and experiments on an oscillating atomic force microscope cantilever approaching a surface, where the intermodulation response of the cantilever driven with two pure harmonic tones is investigated. In the simulations, the tip and surface interact with a conservative nonlinear force, and the parameter space of approach distance and surface stiffness is explored. Approach experiments are carried out on three surfaces with widely varying stiffness. Qualitative similarities between simulations and experiment can be seen, but quantitative comparison is difficult due to the overly idealized tip-surface force model used in the simulation.
