Quadrupolar and Dipolar Excitons in Bilayer 2-MoSe
Shun Feng, Aidan J. Campbell, Bibi Mary Francis +6
We report the experimental observation of quadrupolar exciton states in the reflectance contrast spectrum of 2-stacked bilayer MoSe. The application of a vertical electric f…
The interplay of field-tunable strongly correlated states in a multi-orbital moiré system
Aidan J. Campbell, Valerio Vitale, Mauro Brotons-Gisbert +5
The interplay of charge, spin, lattice, and orbital degrees of freedom leads to a wide range of emergent phenomena in strongly correlated systems. In heterobilayer transition metal…
Highly Tunable Ground and Excited State Excitonic Dipoles in Multilayer 2H-MoSe
Shun Feng, Aidan Campbell, Mauro Brotons-Gisbert +7
The fundamental properties of an exciton are determined by the spin, valley, energy, and spatial wavefunctions of the Coulomb bound electron and hole. In van der Waals materials, t…
Exciton-polarons in the presence of strongly correlated electronic states in a MoSe/WSe moiré superlattice
Aidan J. Campbell, Mauro Brotons-Gisbert, Hyeonjun Baek +5
Two-dimensional moiré materials provide a highly tunable platform to investigate strongly correlated electronic states. Such emergent many-body phenomena can be optically probed in…
Electrically driven strain-induced deterministic single-photon emitters in a van der Waals heterostructure
Jae-Pil So, Ha-Reem Kim, Hyeonjun Baek +8
Quantum confinement in atomically-thin TMDCs enables the realization of deterministic single-photon emitters. The position and polarization control of single photons have been achi…
Optical read-out of Coulomb staircases in a moiré superlattice via trapped interlayer trions
Hyeonjun Baek, Mauro Brotons-Gisbert, Aidan Campbell +5
Moiré patterns with a superlattice potential can be formed by vertically stacking two layered materials with a relative twist or lattice constant mismatch. The moiré superlattice c…
Moiré-trapped interlayer trions in a charge-tunable WSe/MoSe heterobilayer
Mauro Brotons-Gisbert, Hyeonjun Baek, Aidan Campbell +3
Transition metal dichalcogenide heterobilayers offer attractive opportunities to realize lattices of interacting bosons with several degrees of freedom. Such heterobilayers can fea…
Highly tunable quantum light from moiré trapped excitons
Hyeonjun Baek, Mauro Brotons-Gisbert, Zhe Xian Koong +5
Photon antibunching, a hallmark of quantum light, has been observed in the correlations of light from isolated atomic and atomic-like solid-state systems. Two-dimensional semicondu…
Spin-layer locking of interlayer excitons trapped in moiré potentials
Mauro Brotons-Gisbert, Hyeonjun Baek, Alejandro Molina-Sánchez +7
Van der Waals heterostructures offer attractive opportunities to design quantum materials. For instance, transition metal dichalcogenides (TMDs) possess three quantum degrees of fr…
