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…
Advancing atomic electron tomography with neural networks
Juhyeok Lee, Yongsoo Yang
Accurate determination of three-dimensional (3D) atomic structures is crucial for understanding and controlling the properties of nanomaterials. Atomic electron tomography (AET) of…
Atomic-scale 3D structural dynamics and functional degradation of Pt alloy nanocatalysts during the oxygen reduction reaction
Chaehwa Jeong, Juhyeok Lee, Hyesung Jo +6
Pt-based electrocatalysts are the primary choice for fuel cells due to their superior oxygen reduction reaction (ORR) activity. To enhance ORR performance and durability, extensive…
Optical detection of bond-dependent and frustrated spin in the two-dimensional cobalt-based honeycomb antiferromagnet Cu3Co2SbO6
Baekjune Kang, Uksam Choi, Taek Sun Jung +18
Two-dimensional honeycomb antiferromagnet becomes an important class of materials as it can provide a route to Kitaev quantum spin liquid, characterized by massive quantum entangle…
