Observation of surface potential at nanometer scale by electrostatic force microscopy (EFM) with large signals

Materials Science and Engineering: B, 1998
Abstract By polarising the tip of an atomic force microscope (AFM) (in non-contact resonant mode) it is possible to detect local variations in the surface potential of nanostructures. These potential variations are detected by measuring the cantilever flexure produced by the applied signal. This information is obtained at the same time as the classic

Dielectric Nanotomography Based on Electrostatic Force Microscopy: A Numerical Analysis [PDF]

open access: yesJournal of Applied Physics, 2020
Electrostatic force microscopy (EFM) can image nanoscale objects buried below the surface. Here, we theoretically show that this capabilitycan be used to obtain nanotomographic information, i.e., the physical dimensions and dielectric properties, of ...

Nanoparticles Charge Response From Electrostatic Force Microscopy [PDF]

open access: yesApplied Physics Letters, 2013
Electrostatic force microscopy (EFM) allows measurement of tiny changes in tip-sample capacitance. When nanoobjects are studied by EFM, they only contribute a very small fraction of the total capacitance between the tip and the sample.

Electrostatic Force Microscopy and Potentiometry of Realistic Nanostructured Systems

open access: yesJournal of Applied Physics, 2009
We investigate the dependency of electrostatic interaction forces on applied potentials in electrostatic force microscopy (EFM) as well as in related local potentiometry techniques such as Kelvin probe microscopy (KPM).
