Three-dimensional atom-by-atom measurement of interface diffusion dynamics
Doojin Park, Hyesung Jo, Yongmin Kwon +7
Diffusion at interfaces governs how materials and devices form, evolve and function. It is usually measured through smooth concentration profiles and bulk transport coefficients, w…
Correlative 3D Mapping of Structure, Composition, and Valence State Dynamics in Battery Cathodes via Simultaneous ADF-EDS-EELS Tomography
Jaewhan Oh, Sunggu Kim, Chaehwa Jeong +6
Understanding degradation in battery cathodes and other functional materials requires simultaneous knowledge of structural, chemical, and electronic changes in three dimensions (3D…
Spatial correlations of charge density wave order across the transition in 2H-NbSe2
Seokjo Hong, Jaewhan Oh, Jemin Park +7
Charge density waves (CDWs) involve coupled amplitude and phase degrees of freedom, but direct access to local amplitude correlations remains experimentally challenging. Here, we r…
Polymorphic spin ordering in a single-crystalline cobalt-doped Fe3GaTe2
Woohyun Cho, Jaehun Cha, Yoon-Gu Kang +10
A single crystalline system typically stabilizes a unique state for spin ordering below a critical temperature. Certain materials exhibit multiple magnetic states, driven by struct…
Singular Hall response from a correlated ferromagnetic flat nodal-line semimetal
Woohyun Cho, Yoon-Gu Kang, Jaehun Cha +9
Topological quantum phases have been largely understood in weakly correlated systems, which have identified various quantum phenomena such as spin Hall effect, protected transport…
Revealing the Three-Dimensional Arrangement of Polar Topology in Nanoparticles
Chaehwa Jeong, Juhyeok Lee, Hyesung Jo +8
In the early 2000s, low dimensional systems were predicted to have topologically nontrivial polar structures, such as vortices or skyrmions, depending on mechanical or electrical b…
