Electric Force Microscopy Mode

Electric Force Microscopy Mode

Electric Force Microscopy Mode (EFM) is an oscillating mode. A metal tip scans the surface to record the topography. Then, the tip is over the sample and recording the offsets of the phase signal of the interactions with the gradient of electrical forces present on the surface.

Electric field gradient mapping

Electric Force Microscopy (EFM) measures electric field gradient distribution by measuring the electrostatic force between the surface and a biased AFM cantilever. It is used for electrical failure analysis, detecting trapped charges, mapping electric polarization, and performing electrical read…
