Twist Engineering of Anisotropic Excitonic and Optical Properties of a Two-Dimensional Magnetic Semiconductor Open
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 engineering provides a powerful tool to manipulate the fun…

Large exciton binding energy in a bulk van der Waals magnet from quasi-1D electronic localization Open
Excitons, bound electron-hole pairs, influence the optical properties in strongly interacting solid-state systems and are typically most stable and pronounced in monolayer materials. Bulk systems with large exciton binding energies, on the…

Magnetic Exciton-Polariton with Strongly Coupled Atomic and Photonic Anisotropies Open
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 different length scales. Here we demonstrate a matter-light…

Imaging dynamic exciton interactions and coupling in transition metal dichalcogenides Open
Transition metal dichalcogenides (TMDs) are regarded as a possible material platform for quantum information science and related device applications. In TMD monolayers, the dephasing time and inhomogeneity are crucial parameters for any qu…

Nanoscale Trapping of Interlayer Excitons in a 2D Semiconductor Heterostructure Open
For quantum technologies based on single excitons and spins, the deterministic placement and control of a single exciton is a longstanding goal. MoSe2-WSe2 heterostructures host spatially indirect interlayer excitons …
