Hierarchical Relaxation in Large-twist-angle Moire Drives Supermoire Formation
Chuqiao Shi, Giovanny Espitia, Yanxing Li +9
Supermoire lattices in large-angle twisted bilayers have recently been shown to emerge from periodic arrangements of commensurate stacking motifs, yet the microscopic structural me…
BanglaRhet: Benchmarking Classical and Transformer Models for Rhetorical and Persuasion Detection in Bangla Political Speech
Rohit Kumar Sen, Anik Chowdhury
Political discourse often uses rhetorical and persuasive language to frame narratives, influence public opinion, and mobilize audiences. While Bangla natural language processing ha…
Engineering Grain Boundary Commensurability for Ferroelectric Stabilization in Hafnia-Based Films
Chuqiao Shi, Xinyan Li, Xing He +11
Grain boundaries fundamentally dictate the macroscopic properties of polycrystalline materials by breaking long-range symmetry. In ferroelectrics, these structural discontinuities…
Revealing Atomic-Scale Switching Pathways in van der Waals Ferroelectrics
Xinyan Li, Kenna Ashen, Chuqiao Shi +9
Two-dimensional van der Waals (vdW) materials hold the potential for ultra-scaled ferroelectric (FE) devices due to their silicon compatibility and robust polarization down to atom…
Robust Super-Moiré in Large Angle Single-Twist Bilayers
Yanxing Li, Chuqiao Shi, Fan Zhang +19
Forming long wavelength moiré superlattices (MSL) at small-angle twist van der Waals (vdW) bilayers has been a key approach to creating moiré flat bands. The small-angle twist, how…
PEAR: A Robust and Flexible Automation Framework for Ptychography Enabled by Multiple Large Language Model Agents
Xiangyu Yin, Chuqiao Shi, Yimo Han +1
Ptychography is an advanced computational imaging technique in X-ray and electron microscopy. It has been widely adopted across scientific research fields, including physics, chemi…
Preserving Surface Strain in Nanocatalysts via Morphology Control
Chuqiao Shi, Zhihua Cheng, Alberto Leonardi +4
Engineering strain critically affects the properties of materials and has extensive applications in semiconductors and quantum systems. However, the deployment of strain-engineered…
Reversible Non-Volatile Electronic Switching in a Near Room Temperature van der Waals Ferromagnet
Han Wu, Lei Chen, Paul Malinowski +37
The ability to reversibly toggle between two distinct states in a non-volatile method is important for information storage applications. Such devices have been realized for phase-c…
Uncovering Material Deformations via Machine Learning Combined with Four-Dimensional Scanning Transmission Electron Microscopy
Chuqiao Shi, Michael C. Cao, Sarah M. Rehn +5
Understanding lattice deformations is crucial in determining the properties of nanomaterials, which can become more prominent in future applications ranging from energy harvesting…
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…
