Open-loop amplitude-modulation Kelvin probe force microscopy operated in single-pass PeakForce tapping mode

Beilstein Journal of Nanotechnology, 2021
The open-loop (OL) variant of Kelvin probe force microscopy (KPFM) provides access to the voltage response of the electrostatic interaction between a conductive atomic force microscopy (AFM) probe and the investigated sample. The measured response can be

Implementation of data-cube pump–probe KPFM on organic solar cells

Beilstein Journal of Nanotechnology, 2020
An implementation of pump–probe Kelvin probe force microscopy (pp-KPFM) is reported that enables recording the time-resolved surface potential in single-point mode or over a 2D grid. The spectroscopic data are acquired in open z-loop configuration, which

The effect of sample resistivity on Kelvin probe force microscopy [PDF]

, 2012
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.
