Atomistic simulations of atomic force microscopy [PDF]

, 2010
An important milestone in exploration of physical phenomena on the nanometer scale was the invention of scanning tunneling microscopy (STM) in 1982 by G. Binig and H. Rohrer. Later, using noncontact atomic force microscopy (AFM) atomic resolution has

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

Advanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Sol-gel derived ferroelectric nanoparticles investigated by piezoresponse force microscopy

, 2009
Piezoresponse force microscopy PFM was used to investigate the ferroelectric properties of sol-gel derived LiNbO3 nanoparticles. To determine the degree of ferroelectricity we took large-area images and performed statistical image-analysis.

Topography and mechanical properties of single molecules of type I collagen using atomic force microscopy [PDF]

, 2005
Although the mechanical behavior of tendon and bone has been studied for decades, there is still relatively little understanding of the molecular basis for their specific properties.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Model of Frequency-Modulated Atomic Force Microscopy for Non-Contact Piezoresponse Applications

, 2019
Piezoresponse force microscopy (PFM) is a local probe method based on atomic force microscopy (AFM), where a surface displacement of a piezoelectric sample after application of an external electric field can be measured based on its effect on the AFM ...

Ferroelectric domains and phase transition of sol-gel processed epitaxial Sm-doped BiFeO3 (001) thin films

Journal of Materiomics, 2018
BiFeO3, a room-temperature multiferroic material, has recently been increasingly applied as a potential lead-free piezoelectric material due to its large piezoelectricity achieved by doping.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Combined Kelvin probe force microscopy and secondary ion mass spectrometry for hydrogen detection in corroded 2024 aluminium alloy [PDF]

, 2013
The capability of Kelvin probe force microscopy (KFM) to detect and locate hydrogen in corroded 2024 aluminium alloy was demonstrated. Hydrogen was introduced inside the 2024 alloy following a cyclic corrosion test consisting of cycles of immersion in 1 ...
