Appl., 2019, 11, 064020 [10.1103/PhysRevApplied.11.064020][arXiv:1807.01219]. In this 32 page manuscript we show that the usual equations used to describe electrical scanned probe microscopy experiments make assumptions which are not valid for a wide variety of semiconductor samples. We derive new equations for cantilever frequency shift and non-contact electrical friction, written in terms of the sample’s electrical impedance, that are valid for semiconductor samples.
