Noncontact atomic force microscopy II [PDF]

Beilstein Journal of Nanotechnology, 2014
Cataloged from PDF version of article.Background: Highly ordered three-dimensional colloidal crystals (supracrystals) comprised of 7.4 nm diameter Au nanocrystals (with a 5% size dispersion) have been imaged and analysed using a combination of scanning ...

Interpreting motion and force for narrow-band intermodulation atomic force microscopy

Beilstein Journal of Nanotechnology, 2013
Intermodulation atomic force microscopy (ImAFM) is a mode of dynamic atomic force microscopy that probes the nonlinear tip–surface force by measurement of the mixing of multiple modes in a frequency comb.

Shale adhesion force measurements via atomic force microscopy

Oil & Gas Science and Technology, 2021
Wettability of sedimentary rock surface is an essential parameter that defines oil recovery and production rates of a reservoir. The discovery of wettability alteration in reservoirs, as well as complications that occur in analysis of heterogeneous ...

Massively parallel cantilever-free atomic force microscopy

Nature Communications, 2021
Atomic force microscopy (AFM) provides high resolution, but is limited to small areas. Here, the authors introduce a massively parallel AFM approach with >1000 probes in a cantilever-free probe architecture, and present an optical method for detecting ...

Electron scattering in atomic force microscopy experiments [PDF]

, 2005
It has been shown that electron transitions, as measured in a scanning tunnelling microscope (STM), are related to chemical interactions in a tunnelling barrier.

Atomic resolution with high-eigenmode tapping mode atomic force microscopy

Physical Review Research, 2022
Atomic surface structure imaging is instrumental for the understanding of surface-related phenomena. Here, we show that conventional tapping mode atomic force microscopy with high cantilever eigenmodes and subnanometer amplitudes allow routine atomic ...

Potential contributions of noncontact atomic force microscopy for the future Casimir force measurements [PDF]

, 2010
Surface electric noise, i.e., the non-uniform distribution of charges and potentials on a surface, poses a great experimental challenge in modern precision force measurements.
