Wafer-scale Programmed Assembly of One-atom-thick Crystals
Seong-Jun Yang, Ju-Hyun Jung, Eunsook Lee +11
Crystalline films offer various physical properties based on the modulation of their thicknesses and atomic structures. The layer-by-layer assembly of atomically thin crystals prov…
In situ Imaging of an Anisotropic Layer-by-Layer Phase Transition in Few-Layer MoTe2
Chia-Hao Lee, Huije Ryu, Gillian Nolan +9
Understanding the phase transition mechanisms in two-dimensional (2D) materials is a key to precisely tailor their properties at the nanoscale. Molybdenum ditelluride (MoTe2) exhib…
Leveraging generative adversarial networks to create realistic scanning transmission electron microscopy images
Abid Khan, Chia-Hao Lee, Pinshane Y. Huang +1
The rise of automation and machine learning (ML) in electron microscopy has the potential to revolutionize materials research through autonomous data collection and processing. A s…
Disordered Hyperuniform Solid State Materials
Duyu Chen, Houlong Zhuang, Mohan Chen +3
Disordered hyperuniform (DHU) states are recently discovered exotic states of condensed matter. DHU systems are similar to liquids or glasses in that they are statistically isotrop…
Angstrom-Scale Imaging of Magnetization in Antiferromagnetic FeAs via 4D-STEM
Kayla X. Nguyen, Jeffrey Huang, Manohar H. Karigerasi +6
We demonstrate a combination of computational tools and experimental 4D-STEM methods to image the local magnetic moment in antiferromagnetic FeAs with 6 angstrom spatial resolu…
High-resolution diffraction reveals magnetoelastic coupling and coherent phase separation in tetragonal CuMnAs
Manohar H. Karigerasi, Kisung Kang, Jeffrey Huang +6
Tetragonal CuMnAs was the first antiferromagnet where reorientation of the Néel vector was reported to occur by an inverse spin galvanic effect. A complicating factor in the format…
Nearly hyperuniform, nonhyperuniform, and antihyperuniform density fluctuations in two-dimensional transition metal dichalcogenides with defects
Duyu Chen, Yu Zheng, Chia-Hao Lee +5
Hyperuniform many-body systems in -dimensional Euclidean space are characterized by completely suppressed (normalized) infinite-wavelength density fluctuations, and appear to be…
Deep Learning Enabled Strain Mapping of Single-Atom Defects in 2D Transition Metal Dichalcogenides with Sub-picometer Precision
Chia-Hao Lee, Abid Khan, Di Luo +9
2D materials offer an ideal platform to study the strain fields induced by individual atomic defects, yet challenges associated with radiation damage have so-far limited electron m…
Strain Modulation of Graphene by Nanoscale Substrate Curvatures: A Molecular View
Yingjie Zhang, Mohammad Heiranian, Blanka Janicek +7
Spatially nonuniform strain is important for engineering the pseudomagnetic field and band structure of graphene. Despite the wide interest in strain engineering, there is still a…
Selective Area Superconductor Epitaxy to Ballistic Semiconductor Nanowires
S. T. Gill, J. Damasco, B. E. Janicek +7
Semiconductor nanowires such as InAs and InSb are promising materials for studying Majorana zero-modes and demonstrating non-Abelian particle exchange relevant for topological quan…
Multi-terminal electrical transport measurements of molybdenum disulphide using van der Waals heterostructure device platform
Xu Cui, Gwan-Hyoung Lee, Young Duck Kim +15
Atomically thin two-dimensional (2D) semiconductors such as molybdenum disulphide (MoS2) hold great promise in electrical, optical, and mechanical devices and display novel physica…
Strain Solitons and Topological Defects in Bilayer Graphene
Jonathan S. Alden, Adam W. Tsen, Pinshane Y. Huang +5
Spontaneous symmetry-breaking, where the ground state of a system has lower symmetry than the underlying Hamiltonian, is ubiquitous in physics. It leads to multiply-degenerate grou…
Grains and grain boundaries in highly crystalline monolayer molybdenum disulfide
Arend M. van der Zande, Pinshane Y. Huang, Daniel A. Chenet +7
Recent progress in large-area synthesis of monolayer molybdenum disulfide, a new two-dimensional direct-bandgap semiconductor, is paving the way for applications in atomically thin…
