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…
Determining the complex second-order optical susceptibility in macroscale van der Waals heterobilayers
Zeyuan Zhu, Taejun Yoo, Kanchan Shaikh +5
We report on the experimental characterization of the second-order susceptibility in MoSe/WS heterobilayers, including their hidden complex phases. To this end, we develope…
2D material exciton-polariton transport on 2D photonic crystals
Xin Xie, Qiuyang Li, Chenxi Liu +4
Transport of elementary excitations is a fundamental property of 2D semiconductors, important for wide-ranging emergent phenomena and device applications. While exciton transport r…
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…
