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 ...

EFM data mapped into 2D images of tip-sample contact potential difference and capacitance second derivative [PDF]

open access: yes, 2013
We report a simple technique for mapping Electrostatic Force Microscopy (EFM) bias sweep data into 2D images. The method allows simultaneous probing, in the same scanning area, of the contact potential difference and the second derivative of the ...

Exploiting the interaction area limitation in Electrostatic Force Microscopy for dielectric measurements of nanoparticles

open access: yesMicro and Nano Engineering
Electrostatic Force Microscopy (EFM) is widely used to determine the dielectric constant of 3D-nanostructures. Achieving quantitative results often requires complex Finite Element Method(FEM)-simulations, is limited by topographic crosstalk and tip ...

Deep learning-assisted ultrafast ferroelectric domain imaging using atomic force microscopy

open access: yesnpj Computational Materials
Piezoresponse force microscopy (PFM), a lock-in-based mode of atomic force microscopy (AFM), enables sensitive ferroelectric domain imaging. However, fast imaging for either massive measurements or studying fast dynamic behavior remains challenging ...

Variable frequency and quantitative capacitance measurements in dual bias modulation electrostatic force microscopy [PDF]

open access: yes
Electrostatic force microscopy (EFM) has been used to investigate the local electronic properties of materials, although frequency response and quantitative capacitance measurements are difficult in conventional EFM because of its narrow measurement ...

KP-EFM measurements of surface potential and work function of doped graphene

open access: yes, 2013
The electronic properties of graphene sheets have recently attracted much experimental and theoretical interest. A single graphene layer is a semimetal or zero-gap semiconductor, and has excellent electronic properties, such as high mobility (200 000 cm2
