Kelvin probe force microscopy for local characterisation of active nanoelectronic devices [PDF]
Beilstein Journal of Nanotechnology, 2015 Frequency modulated Kelvin probe force microscopy (FM-KFM) is the method of choice for high resolution measurements of local surface potentials, yet on coarse topographic structures most researchers revert to amplitude modulated lift-mode techniques for ...

Quantitative AC - Kelvin Probe Force Microscopy
Microelectronic Engineering, 2017 This paper presents a novel feedback based Scanning Probe Microscopy method which enables quantitative surface potential measurements without the need of the DC bias of Kelvin Probe Force Microscopy. In addition to the sinusoidal excitation signal at frequency , a sinusoidal signal with the frequency 2 is applied to the conductive cantilever.

Kelvin probe force microscopy for material characterization [PDF]
Microscopy, 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.
