Kelvin probe force microscopy for material characterization [PDF]

open access: yesMicroscopy, 2022
Abstract Kelvin probe force microscopy is a scanning probe method for imaging the surface potential by atomic force microscopy. The surface potential is one of the most important surface properties and is correlated to e.g. the work function, surface dipoles, localized surface charges and structural properties.

Modelling and experimental verification of tip-induced polarization in Kelvin probe force microscopy measurements on dielectric surfaces [PDF]

open access: yes, 2015
Kelvin probe force microscopy is a widely used technique for measuring surface potential distributions on the micro- and nanometer scale. The data are, however, often analyzed qualitatively, especially for dielectrics.
