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…
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…
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…
Twist Angle Dependent Interlayer Exciton Lifetimes in van der Waals Heterostructures
Junho Choi, Matthias Florian, Alexander Steinhoff +15
In van der Waals (vdW) heterostructures formed by stacking two monolayers of transition metal dichalcogenides, multiple exciton resonances with highly tunable properties are formed…
