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…
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…
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…
