Hierarchical Relaxation in Large-twist-angle Moire Drives Supermoire Formation
Chuqiao Shi, Giovanny Espitia, Yanxing Li +9
Supermoire lattices in large-angle twisted bilayers have recently been shown to emerge from periodic arrangements of commensurate stacking motifs, yet the microscopic structural me…
Electrical Probing of Dark Excitons through Microwave Permittivity
Alex Stram, Zhida Liu, Ziheng Zhang +17
Excitons in atomically thin semiconductors are almost always probed through their optical signatures, because the short lifetimes of these transient quasiparticles are generally as…
Robust Super-Moiré in Large Angle Single-Twist Bilayers
Yanxing Li, Chuqiao Shi, Fan Zhang +19
Forming long wavelength moiré superlattices (MSL) at small-angle twist van der Waals (vdW) bilayers has been a key approach to creating moiré flat bands. The small-angle twist, how…
Valley-mediated singlet- and triplet-polaron interactions and quantum dynamics in a doped WSe monolayer
Yue Ni, Di Huang, Danfu Liang +11
In doped transition metal dichalcogenides, optically created excitons (bound electron-hole pairs) can strongly interact with a Fermi sea of electrons to form Fermi polaron quasipar…
Field-Tunable Valley Coupling and Localization in a Dodecagonal Semiconductor Quasicrystal
Zhida Liu, Qiang Gao, Yanxing Li +11
Quasicrystals are characterized by atomic arrangements possessing long-range order without periodicity. Van der Waals (vdW) bilayers provide a unique opportunity to controllably va…
Emergent Trion Resonance Driven by Lattice Reconstruction in a Moiré Superlattice
Zhida Liu, Haonan Wang, Xiaohui Liu +20
We investigate how many-electron excited states emerge in twisted MoSe2 homobilayers when the lattice reconstructions evolve. Notably, we identify a new trion resonance that arises…
Experimental signature of layer skyrmions and implications for band topology in twisted WSe2 bilayers
Fan Zhang, Nicolás Morales-Durán, Yanxing Li +13
Transition metal dichalcogenide (TMD) twisted homobilayers have been established as an ideal platform for studying strong correlation phenomena, as exemplified by the recent discov…
An active metasurface enhanced with moiré ferroelectricity
Dong Seob Kim, Chengxin Xiao, Roy C. Dominguez +11
Semiconductor moiré systems, characterized by their periodic spatial light emission, unveil a new paradigm of active metasurfaces. Here, we show that ferroelectric moiré domains fo…
Atomistic Control in Molecular Beam Epitaxy Growth of Intrinsic Magnetic Topological Insulator MnBi2Te4
Hyunsue Kim, Mengke Liu, Lisa Frammolino +13
Intrinsic magnetic topological insulators have emerged as a promising platform to study the interplay between topological surface states and ferromagnetism. This unique interplay c…
Electrostatic moiré potential from twisted-hBN layers
Dong Seob Kim, Roy C. Dominguez, Rigo Mayorga-Luna +17
Moiré superlattices formed by vertically stacking van der Waals layers host a rich variety of correlated electronic phases and function as novel photonic materials. The moiré poten…
All Electrical Control and Temperature Dependence of the Spin and Valley Hall Effect in Monolayer WSe2 Transistors
Xintong Li, Zhida Liu, Yihan Liu +4
Heavy metal-based two-dimensional van der Waals materials have a large, coupled spin and valley Hall effect (SVHE) that has potential use in spintronics and valleytronics. Optical…
