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…

Bichromatic Moiré Superlattices for Tunable Quadrupolar Trions and Correlated States
Mingfeng Chen, Runtong Li, Haonan Wang +11
Moiré superlattices in transition metal dichalcogenide heterostructures provide a platform to engineer many-body interactions. Here, we realize a bichromatic moiré superlattice in…

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…
