Layered van der Waals materials have risen as powerful platforms to artificially engineer correlated states of matter. Here we show the emergence a multiferroic order in twisted dichalcogenide bilayer superlattice at quarter-filling. We that competition between Coulomb interactions leads simultaneous ferrimagnetic and ferroelectric orders. derive magnetoelectric coupling for this system, which ...

Small-twist-angle transition metal dichalcogenide (TMD) heterobilayers develop isolated flat moir\'e bands that are approximately described by triangular lattice generalized Hubbard models [PhysRevLett.121.026402]. In this article we explore the metallic and insulating states appear under different control conditions at a density of one-electron per period, transitions between them. By combinin...

Novel physical phenomena can emerge in low-dimensional nanomaterials. Bulk MoS2, a prototypical metal dichalcogenide, is an indirect bandgap semiconductor with negligible photoluminescence. When the MoS2 crystal is thinned to monolayer, however, a strong photoluminescence emerges, indicating an indirect to direct bandgap transition in this d-electron system. This observation shows that quantum ...

Abstract Transition metal dichalcogenides have been the subject of numerous studies addressing technological applications and fundamental issues. Single-layer PtSe 2 is a semiconductor with trivial bandgap, in contrast, its counterpart 25 % </mml:ma...

2D nanomaterials, including graphene, transition metal oxide (TMO) nanosheets, transition metal dichalcogenide (TMD) nanosheets, etc., have offered an appealing and unprecedented opportunity for the development of high-performance electrode materials for lithium-ion batteries (LIBs). Although significant progress has been made on 2D nanomaterials for LIB applications in the recent years, some m...
