Unambiguous interpretation of atomically resolved force microscopy images of an insulator [PDF]

open access: yes, 2001
The (111) surface of CaF 2 was imaged with dynamic mode scanning force microscopy and modeled using atomistic simulation. Both experiment and theory showed a clear triangular contrast pattern in images, and theory demonstrated that the contrast pattern ...

Measurement of electrostatic tip–sample interactions by time-domain Kelvin probe force microscopy

open access: yesBeilstein Journal of Nanotechnology, 2020
Kelvin probe force microscopy is a scanning probe technique used to quantify the local electrostatic potential of a surface. In common implementations, the bias voltage between the tip and the sample is modulated.

Electrostatically-blind quantitative piezoresponse force microscopy free of distributed-force artifacts

open access: yesNanoscale Advances, 2022
Electrostatic forces complicate the interpretation of piezoresponse force microscopy (PFM). Electrostatic blind spot (ESBS) PFM overcomes these complications by placing the detection laser where it is sensitive piezoresponse but not electrostatics.

Electrostatic charging artefacts in Lorentz electron tomography of MFM tip stray fields [PDF]

open access: yes, 2001
Using the technique of differential phase contrast (DPC) Lorentz electron microscopy, the magnetic stray field distribution from magnetic force microscopy (MFM) tips can be calculated in a plane in front of the tip using tomographic reconstruction ...

Nonlinear analysis of Electrostatic Force Microscopy

open access: yesAIP Conference Proceedings, 2003
In a search to control charge injection and detection with an atomic force microscope, dynamic force curves are investigated in the presence of an electrostatic tip‐sample coupling. An analytical study, using a plane capacitor model, provides results in good agreement with experimental data, in particular for the hysteretic behavior of the tip ...

Calculating electrostatic interactions in atomic force microscopy with semiconductor samples

open access: yesAIP Advances, 2019
Electrostatic interactions are important in non-contact atomic force microscopy (AFM) measurement. Previous reports had focused on the calculation of electrostatic interactions in AFM with metal and dielectric samples, and the present work extended the ...
