Moiré band theory for M-valley twisted transition metal dichalcogenides
Chao Lei, Perry T. Mahon, Allan H. MacDonald
We propose twisted bilayers of certain group IV and IVB trigonal transition metal dichalcogenides (TMDs) MX (MZr, Hf, Sn and XS, Se) as moiré materials. In monolayer f…
Near room temperature magnetoelectric response and tunable magnetic anisotropy in the two-dimensional magnet 1T-CrTe2
Fengping Li, Bheema Lingam Chittari, Chao Lei +1
Magnets with controllable magnetization and high critical temperature are essential for practical spintronics devices, among which the two-dimensional 1T-CrTe2 stands out because o…
Capacitive scheme to detect the topological magnetoelectric effect
Chao Lei, Perry T. Mahon, C. M. Canali +1
The topological magnetoelectric effect (TME) is a defining property of three-dimensional topological insulators that was predicted on theoretical grounds more than…
All-optical magnetic imaging with spin defects in van der Waals materials at Angstrom-scale
Ning Wang, Jianming Cai, Chao Lei
Magnetic imaging with ultra-high spatial resolution is crucial to exploring the magnetic textures of emerging quantum materials. We propose a novel magnetic imaging protocol that a…
