Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Inversion of In-situ Stress Field of Large Underground Cavern Group in Complex Geology Methods and Applications

工程科学与技术
Deep valleys and large structural planes considerably affect the distribution of the in-situ stress field in large underground caverns. Accurate prediction of the in-situ stress field in underground caverns is crucial for engineering construction.

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, EarlyView.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Tectonic Stylolite Stress Inversion, Angle Correction, Validation Across Scales and Variability Within Outcrops

Geosciences
Quantitative stylolite roughness inversion technique (SRIT) is a powerful tool that is increasingly used to determine burial depth and tectonic stress of rocks that contain stylolites. Despite the increasing use of SRIT, there is still a need to validate

Volcano-tectonic interactions revealed by inversion of focal mechanisms: stress field insight around and beneath the Vatnajökull ice cap in Iceland

Frontiers in Earth Science, 2014
Volcano-tectonic processes in the central part of Iceland, covered by the Vatnajökull glacier, are investigated by inversion of focal mechanisms. Working on a large catalogue of focal mechanisms determined by the Icelandic Meteorological Office, we used ...

Crustal kinematics and stress fields in the Southeast Yunnan Arcuate Structural Belt: insights from geological field surveys, stress field inversion, and numerical simulation

International Geology Review
The Southeast Yunnan Arcuate Structural Belt, a complex tectonic region at the southeastern margin of the Tibetan Plateau, has been significantly influenced by the India – Eurasia collision. The debates regarding its Cenozoic deformation history and the intricate dynamics between crustal deformation and mantle processes remain ongoing.

Effect of interface inversion on thermal stress field in CZ crystal growth of oxide.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1990
For CZ crystal growth of an oxide (Al2O5), finite element analyses of the thermal stress field in the crystal are carried out, and the effect of interface shape on the maximum shear stress in the crystal is investigated.When the crystal rotation rate increases, with other operating conditions unchanged, the melt/crystal interface changes its shape from
