In both analyses, the average contribution of the capacitive coupling of the AFM cantilever to the electrostatic interaction was separated by

Because the entire AFM probe (tip and cantilever) is conductive, a significant contribution to this force comes from the capacitive coupling between the cantilever and the sample region underneath the cantilever. As such, when the tip images a region with a surface

• capacitive coupling is highly mitigated in CL FM-KPFM variants, which operate on nullifying the electrostatic force gradient between tip and sample. In KPFM gradient detection methods, the almost linear distance-dependent force between cantilever and sample is mostly removed from the measured CPD [47][50][64
