The effect of sample resistivity on Kelvin probe force microscopy

(author unknown)



A. J. Weymouth and F. J. Giessibl

Kelvin probe force microscopy (KPFM) is a powerful technique to probe the local electronic structure of materials with atomic force microscopy. One assumption often made is that the applied bias drops fully in the tip-sample junction. We have recently identified an effect, the Phantom force, which ... [Appl. Phys.
