Imaging the electron charge density in monolayer MoS2 at the Ångstrom scale
Joel Martis, Sandhya Susarla, Archith Rayabharam +15
Four-dimensional scanning transmission electron microscopy (4D-STEM) has recently gained widespread attention for its ability to image atomic electric fields with sub-Ångstrom spat…
Indefinite and Bidirectional Near Infrared Nanocrystal Photoswitching
Changhwan Lee, Emma Z. Xu, Kevin W. C. Kwock +14
Materials whose luminescence can be switched by optical stimulation drive technologies ranging from superresolution imaging1-4, nanophotonics5, and optical data storage6-8, to targ…
Real-time 3D analysis during electron tomography using tomviz
Jonathan Schwartz, Chris Harris, Jacob Pietryga +13
The demand for high-throughput electron tomography is rapidly increasing in biological and material sciences. However, this 3D imaging technique is computationally bottlenecked by…
Hyperspectral imaging of excitons within a moiré unit-cell with a sub-nanometer electron probe
Sandhya Susarla, Mit H. Naik, Daria D. Blach +9
Electronic and optical excitations in two-dimensional moiré systems are uniquely sensitive to local atomic registries, leading to materials- and twist-angle specific correlated ele…
Strong structural and electronic coupling in metavalent PbS moire superlattices
Yu Wang, Zhigang Song, Jiawei Wan +7
Moire superlattices are twisted bilayer materials, in which the tunable interlayer quantum confinement offers access to new physics and novel device functionalities. Previously, mo…
Revealing 3-dimensional core-shell interface structures at the single-atom level
Hyesung Jo, Dae Han Wi, Taegu Lee +12
Nanomaterials with core-shell architectures are prominent examples of strain-engineered materials, where material properties can be designed by fine-tuning the misfit strain at the…
Solving Complex Nanostructures With Ptychographic Atomic Electron Tomography
Philipp M Pelz, Sinead Griffin, Scott Stonemeyer +6
Transmission electron microscopy (TEM) is a potent technique for the determination of three-dimensional atomic scale structure of samples in structural biology and materials scienc…
Symmetry-Breaking and Self-Sorting in Block Copolymer-based Multicomponent Nanocomposites
Le Ma, Hejin Huang, Peter Ercius +2
Co-assembly of inorganic nanoparticles (NPs) and nanostructured polymer matrix represents an intricate interplay of enthalpic or entropic forces. Particle size largely affects the…
Deep Learning Coherent Diffractive Imaging
Dillan J. Chang, Colum M. O'Leary, Cong Su +5
We report the development of deep learning coherent electron diffractive imaging at sub-angstrom resolution using convolutional neural networks (CNNs) trained with only simulated d…
Hard ferromagnetism down to the thinnest limit of iron-intercalated tantalum disulfide
Samra Husremović, Katherine Inzani, Catherine K. Groschner +11
Two-dimensional (2D) magnetic crystals hold promise for miniaturized and ultralow power electronic devices that exploit spin manipulation. In these materials, large, controllable m…
Pervasive beyond room-temperature ferromagnetism in a doped van der Waals magnet: Ni doped FeGeTe with up to 478 K
Xiang Chen, Yu-Tsun Shao, Rui Chen +10
The existence of long range magnetic order in low dimensional magnetic systems, such as the quasi-two-dimensional (2D) van der Waals (vdW) magnets, has attracted intensive studies…
Atomic-scale identification of the active sites of nanocatalysts
Yao Yang, Jihan Zhou, Zipeng Zhao +15
Alloy nanocatalysts have found broad applications ranging from fuel cells to catalytic converters and hydrogenation reactions. Despite extensive studies, identifying the active sit…
