Person–environment misfit

peer reviewedMisfit occurs when an employee’s characteristics are incompatible with those of their work environment. The term “misfit” conveys a sense of a mismatch, of being out of place or different in an unsettling way, and studies indicate that such ...

Atomistic modelling of interaction between dislocations and misfit interface

, 2003
Mechanisms responsible for the formation of a misfit dislocation in a lattice-mismatched system -that involve gliding of the dislocation to the misfit interface-have been studied using Molecular Dynamics simulations of a two-dimensional Lennard-Jones

When Mechanics Rewrites Chemistry: Divergent Pathways of Hardening and Softening in High Strength Al‐Alloys

Advanced Science, EarlyView.
Mechanics reshapes chemistry: plastic flow actively governs two divergent, atomic‐scale mechanochemical pathways that tailor strain localization and ductility in high‐strength 7xxx Al alloys. Rather than relying on static structures, deformation dynamically reinforces the solution‐treated state via clustering, yet destabilizes the peak‐aged condition ...

Misfit-dependent interaction mechanisms between γ-phase dislocations and interfacial dislocation networks in nickel-based single crystal superalloys under [001] tensile loading

Materials & Design
Understanding the dislocation–interface interaction mechanisms at atomic-scale is crucial for improving the temperature capacity of Ni-based single-crystal superalloys.

A first principles investigation on the mechanism of TiC act as heterogeneous nucleation substrate of Mg phase to refine grains in AZ91

AIP Advances, 2019
The lattice misfit of small Miller indices crystal faces between Mg and TiC is calculated based on Bramfitt two-dimensional lattice misfit theory.

Freestanding PZT Films for Integrated Wearable Sensing and Intelligent Acoustic Recognition

Advanced Science, EarlyView.
A freestanding epitaxial PZT/LaNiO3/Pt heterostructure is achieved via water‐assisted delamination from mica, effectively eliminating substrate‐induced clamping and releasing intrinsic ferroelectricity. The released film exhibits substantially enhanced remanent polarization and piezoelectric response, delivering excellent mechanical flexibility and ...

Modeling of stresses and electric fields in piezoelectric multilayer: Application to multi quantum wells

AIP Advances, 2017
Exact closed-form expressions have been derived for the stresses and the electric fields induced in piezoelectric multilayers deposited on a substrate with lattice misfit and thermal expansion coefficient mismatch.

Temperature-Dependent Accommodation of Two Lattices of Largely Different Size during Growth

Nanomaterials, 2019
If a material grows on another material with a largely different lattice constant, which of the two adapts for an energetically favorable growth? To tackle this question, we investigate the growth of Ag on Cu(111) by variable temperature scanning ...

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

Advanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...
