Multifunctional Antiferromagnetic Materials with Giant Piezomagnetism and Noncollinear Spin Current
Hai-Yang Ma, Mengli Hu, Nana Li +4
We propose a new type of spin-valley locking (SVL), named -paired SVL, in antiferromagnetic systems, which directly connects the spin/valley space with the real space,…
One-Dimensional Moiré Excitons in Transition-Metal Dichalcogenide Heterobilayers
Yusong Bai, Lin Zhou, Jue Wang +15
The formation of interfacial moiré patterns from angular and/or lattice mismatch has become a powerful approach to engineer a range of quantum phenomena in van der Waals heterostru…
Magnetic Proximity Effect in a van der Waals Moiré Superlattice
Qingjun Tong, Mingxing Chen, Wang Yao
We investigate the magnetic proximity effect in van der Waals heterostructure formed by a monolayer semiconductor stacked on a 2D ferromagnet, where the lattice mismatch and twisti…
Unusual Exciton-Phonon Interactions at van der Waals Engineered Interfaces
Colin M. Chow, Hongyi Yu, Aaron M. Jones +6
Raman scattering is a ubiquitous phenomenon in light-matter interactions which reveals a material's electronic, structural and thermal properties. Controlling this process would en…
Phonon-assisted oscillatory exciton dynamics in monolayer MoSe2
Colin M. Chow, Hongyi Yu, Aaron M. Jones +6
In monolayer semiconductor transition metal dichalcogenides, the exciton-phonon interaction is expected to strongly affect the photocarrier dynamics. Here, we report on an unusual…
Topological mosaic in Moiré superlattices of van der Waals heterobilayers
Qingjun Tong, Hongyi Yu, Qizhong Zhu +3
Van der Waals (vdW) heterostructures formed by 2D atomic crystals provide a powerful approach towards designer condensed matter systems. Incommensurate heterobilayers with small tw…
