Robustness of attractors in tapping mode atomic force microscopy

Abstract: In this work, we perform a comprehensive analysis of the robustness of attractors in tapping mode atomic force microscopy. The numerical model is based on cantilever dynamics driven in the Lennard-Jones potential. Pseudo-arc-length continuation and basins of attraction are utilized to obtain the frequency response and dynamical integrity of the attractors. The global bifurcation and response scenario maps for the system are developed by incorporating several local bifurcation loci in the excitation parameter s… Show more

“…Their method could effectively improve the subsurface imaging sensitivity of UAFM. 5 In order to verify the reliability of UAFM, Cadena et al used the second-harmonic Kelvin probe force microscopy (KPFM) and UAFM to F I G U R E 1 Schematic verification of TM-AFM phase imaging in subsurface sensitivity. (A) FIB was used to etch steps at the depths of 100, 200 and 300 nm on the silicon wafer surface, and the round holes with different diameters at the depth of 50 nm were etched on the step surface.…”

“…The efficiency of the basin stability method in comparison to the basins of attractions is especially visible when the dimension of phase space is larger than two. In such a case, the classical approach requires much larger computational effort and interpretation of results is very complex (necessity of projections of results on two dimensional cross-sections of multi-dimensional phase space) [33][34][35] . The basin stability method gives statistical information on existing solutions (the volume of basins of attractions in relation to the total volume of considered phase space) and their location in the phase space.…”
