Scanning Kelvin Probe Microscope

VS-SKP - Ametek Scientific Instruments (Ametek SI)

The Kelvin Probe experiment uses a nondestructive method to determine the relative work function difference between the probe and the sample. Work function describes the energy required to liberate an electron from the surface of a conductor; electrochemists often interpret this as the difference from an electrode’s Fermi Level, average energy of electrons, and that of vacuum.
