A simple KPFM-based approach for electrostatic free topographic measurements: the case of MoS2 on SiO2

open access: yes, 2022
International audienceA simple implementation of Kelvin probe force microscopy is reported that enables recording topographic images in the absence of any component of the electrostatic force. Our approach is based on a close loop z-spectroscopy operated

MOVPE-Grown Quantum Cascade Laser Structures Studied by Kelvin Probe Force Microscopy

open access: yesCrystals, 2020
A technique for direct study of the distribution of the applied voltage within a quantum cascade laser (QCL) has been developed. The detailed profile of the potential in the laser claddings and laser core region has been obtained by gradient scanning ...

Measurement of polarization effects in dual-phase ceria-based oxygen permeation membranes using Kelvin probe force microscopy

open access: yesBeilstein Journal of Nanotechnology, 2021
In this study, a dual phase composite (CSO-FC2O) consisting of 60 vol % Ce0.8Sm0.2O1.9 as oxygen-conductive phase and 40 vol % FeCo2O4 as electron-conductive phase was synthesized.

Defects in oxide surfaces studied by atomic force and scanning tunneling microscopy

open access: yesBeilstein Journal of Nanotechnology, 2011
Surfaces of thin oxide films were investigated by means of a dual mode NC-AFM/STM. Apart from imaging the surface termination by NC-AFM with atomic resolution, point defects in magnesium oxide on Ag(001) and line defects in aluminum oxide on NiAl(110 ...

(Invited) Tip Cleaning and Sample Design for High Resolution MOSCAP x-KPFM

open access: yes, 2010
Kelvin probe force microscopy (KPFM) is a unique technique that can provide two dimensional potential profiles inside a working device. A procedure is described to obtain high-resolution KPFM results on ultra-high vacuum (UHV) cleaved III-V MOSCAPs ...
