“…The way how multiple nanowires contribute to the measured electric force in SDM merits some comments, since it is not trivial due to the relatively large size of the nanowires and to the strong dependence of the electrostatic force on the depth position. 40 Again, the situation is very different from what would occur for CNTs in nanocomposites, 29,36 since they are much smaller in diameter. To analyze the electric force generated by crossing nanowires we have considered a model like the one in Fig.…”

“…When the vertical separation of the nanowires is smaller than their diameter, a second effect could also play a role, namely, the capacitive coupling between the nanowires. 40 Due to the capacitive coupling some of the electrostatic energy provided to the system is stored between the nanowires, and hence the electric force acting on the tip is reduced with respect to the simple addition of electric forces due to each separate nanowire. In the present study, we could not identify clearly this effect, since it was masked by a much larger effect due to the local surface topography modification induced by the crossing wires.…”

“…Meanwhile, the last decade has witnessed a growing interest in extending the AFM measurements beyond the sample's surface to probe subsurface properties in complex multiphase nanostructures, by exploring a wide range of AFM configurations and modes. [1] Methods reported in the literature have covered local mechanical properties of the underlying systems such as biological cells, [2,3] interfacial properties related to induced mismatching stresses or local charges or dipoles formation, [4][5][6] charge carriers and doping properties, [7] embedded structures of different chemistries such as polymers or thin films, [8][9][10][11] carbon nanotubes (CNTs) and nanowires (NWs), [12][13][14][15] 2D materials, [16] nanoparticles (NPs), [17,18] and embedded air cavities [19] or confined water structures. [20] These works have explored the capabilities of the AFM to probe the evolving changes in the mechanical deflection of the cantilever or the dynamic vibrational amplitudes, [3,6,8,16] the frequency variations of acoustically generated signals, [19,21,22] microwave signals, [18,23,24] near-field infrared signal, [25] and electrostatic fields.…”

[12][13][14][15][26][27][28][29][30] In parallel, the quantification of the dielectric constant of multiphase nanomaterials has recently gained increasing interest owing to its high importance in 3D heterostructure interconnects and embedded inclusions of nanostructures (nanotubes, nanowires, nanoparticles, and 2D materials). [15,17,31,32] Several works have been reported on the measurement of the dielectric constant using AFMbased methods, which fall into two main categories.…”
