Simultaneous quantitative imaging of surface and magnetic forces
Daniel Forchheimer, Daniel Platz, Erik A. Tholen +1
We demonstrate quantitative force imaging of long-range magnetic forces simultaneously with near-surface van-der-Waals and contact-mechanics forces using intermodulation atomic for…
Polynomial force approximations and multifrequency atomic force microscopy
Daniel Platz, Daniel Forchheimer, Erik A. Tholen +1
We present polynomial force reconstruction from experimental intermodulation atomic force microscopy (ImAFM) data. We study the tip-surface force during a slow surface approach and…
Interpreting motion and force for narrow-band intermodulation atomic force microscopy
Daniel Platz, Daniel Forchheimer, Erik A. Tholén +1
Intermodulation atomic force microscopy (ImAFM) is a mode of dynamic atomic force microscopy that probes the nonlinear tip-surface force by measurement of the mixing of multiple to…
Interaction imaging with amplitude-dependence force spectroscopy
Daniel Platz, Daniel Forchheimer, Erik A. Tholen +1
Knowledge of surface forces is the key to understanding a large number of processes in fields ranging from physics to material science and biology. The most common method to study…
The Role of Nonlinear Dynamics in Quantitative Atomic Force Microscopy
Daniel Platz, Daniel Forchheimer, Erik A. Tholén +1
Various methods of force measurement with the Atomic Force Microscope (AFM) are compared for their ability to accurately determine the tip-surface force from analysis of the nonlin…
The Intermodulation Lockin Analyzer
Erik A. Tholen, Daniel Platz, Daniel Forchheimer +4
Nonlinear systems can be probed by driving them with two or more pure tones while measuring the intermodulation products of the drive tones in the response. We describe a digital l…
