Observation of Ferromagnetic Phase in the Second Moiré Band of Twisted MoTe2
Liheng An, Haiyang Pan, Wen-Xuan Qiu +13
Flat bands and electron correlation in moiré lattices give rise to many exotic phases, including Mott insulators, superconductivity, and topological states. Within the first moiré…
Unconventional ferroelectricity in half-filling states of antiparallel stacking of twisted WSe2
Liheng An, Zishu Zhou, Xuemeng Feng +9
Abstract: We report on emergence of an abnormal electronic polarization in twisted double bilayer WSe2 in antiparallel interface stacking geometry, where local centrosymmetry of at…
Lattice reconstruction induced multiple ultra-flat bands in twisted bilayer WSe2
En Li, Jin-Xin Hu, Xuemeng Feng +5
Moiré superlattices in van der Waals heterostructures provide a tunable platform to study emergent properties that are absent in the natural crystal form. Twisted bilayer transitio…
Giant nonlinear Hall effect in twisted WSe
Meizhen Huang, Zefei Wu, Jinxin Hu +8
The recently discovered nonlinear Hall effect (NHE) in a few non-interacting systems provides a novel mechanism to generate second harmonic electrical Hall signals under time-rever…
Interaction effects and superconductivity signatures in twisted double-bilayer WSe
Liheng An, Xiangbin Cai, Meizhen Huang +6
Twisted bilayer graphene provides a new two-dimensional platform for studying electron interaction phenomena and flat band properties such as correlated insulator transition, super…
Intrinsic valley Hall transport in atomically thin MoS2
Zefei Wu, Benjamin T. Zhou, Gui-Bin Liu +10
Electrons hopping in two-dimensional honeycomb lattices possess a valley degree of freedom in addition to charge and spin. In the absence of inversion symmetry, these systems were…
