Reconstruction of tip-surface interactions with multimodal intermodulation atomic force microscopy
Reconstruction of tip-surface interactions with multimodal intermodulation atomic force microscopy
We propose a theoretical framework for reconstructing tip-surface interactions using the intermodulation technique when more than one eigenmode is required to describe the cantilever motion. Two particular cases of bimodal motion are studied numerically: one bending and one torsional mode, and two bending modes. We demonstrate the possibility of accurate …
