Revealing Strain and Disorder in Transition-Metal Dichalcogenides Using Hyperspectral Photoluminescence Imaging
Adam Alfrey, Cole Tait, Takashi Taniguchi +2
Hyperspectral photoluminescence (HSPL) imaging provides spatially resolved spectral information for monolayer transition-metal dichalcogenides (TMDs), enabling the detection of sub…
Magneto-Moiré Excitons in Twisted Bilayer CrSBr
Qiuyang Li, Anton Shubnic, Nishkarsh Agarwal +15
Moiré superlattices in van der Waals materials have revolutionized the study of electronic and excitonic systems by creating periodic electrostatic potentials. Extending this conc…
Imaging dynamic exciton interactions and coupling in transition metal dichalcogenides
Torben L. Purz, Eric W. Martin, William G. Holtzmann +6
Transition metal dichalcogenides (TMDs) are regarded as a possible materials platform for quantum information science and related device applications. In TMD monolayers, the dephas…
Twist Engineering of Anisotropic Excitonic and Optical Properties of a Two-Dimensional Magnetic Semiconductor
Qiuyang Li, Xiaohan Wan, Senlei Li +12
Two dimensional (2D) van der Waals (vdW) magnetic semiconductors are a new class of quantum materials for studying the emergent physics of excitons and spins in the 2D limit. Twist…
Magnetic Exciton-Polariton with Strongly Coupled Atomic and Photonic Anisotropies
Qiuyang Li, Xin Xie, Adam Alfrey +10
Anisotropy plays a key role in science and engineering. However, the interplay between the material and engineered photonic anisotropies has hardly been explored due to the vastly…
Inhomogeneous saturation of excitons in monolayer transition-metal dichalcogenides
Blake T. Hipsley, Adam Alfrey, Steven T. Cundiff
The paper studies how the apparent inhomogeneous broadening of exciton resonances in monolayer transition‑metal dichalcogenides changes with excitation fluence, using two‑dimension…
