Imaging the electron charge density in monolayer MoS2 at the à ngstrom 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-Ã ngstrom spa…
Designing Artificial Two-Dimensional Landscapes via Room-Temperature Atomic-Layer Substitution
Yunfan Guo, Yuxuan Lin, Kaichen Xie +21
Manipulating materials with atomic-scale precision is essential for the development of next-generation material design toolbox. Tremendous efforts have been made to advance the com…
Molecular monolayer stabilizer for multilayer 2D materials
Cong Su, Zongyou Yin, Qing-Bo Yan +15
2D van der Waals materials have rich and unique functional properties, but many are susceptible to corrosion under ambient conditions. Here we show that linear alkylamines are high…
Tuning color centers at a twisted interface
Cong Su, Fang Zhang, Salman Kahn +15
Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Emp…
Direct Observation of Massless Excitons and Linear Exciton Dispersion
Luna Y. Liu, Steffi Y. Woo, Jinyuan Wu +3
Excitons -- elementary excitations formed by bound electron-hole pairs -- govern the optical properties and excited-state dynamics of materials. In two-dimensions (2D), excitons ar…
Multi-dimensional Fair Federated Learning
Cong Su, Guoxian Yu, Jun Wang +3
Federated learning (FL) has emerged as a promising collaborative and secure paradigm for training a model from decentralized data without compromising privacy. Group fairness and c…
