Wigner Molecular Crystals from Multi-electron Moiré Artificial Atoms
Hongyuan Li, Ziyu Xiang, Aidan P. Reddy +10
Semiconductor moiré superlattices provide a versatile platform to engineer new quantum solids composed of artificial atoms on moiré sites. Previous studies have mostly focused on t…
Electrically controlled interlayer trion fluid in electron-hole bilayers
Ruishi Qi, Qize Li, Zuocheng Zhang +12
The combination of repulsive and attractive Coulomb interactions in a quantum electron(e)-hole(h) fluid can give rise to novel correlated phases of multiparticle charge complexes s…
Twist Angle Dependence of Exciton Resonances in WSe/MoSe Moiré Heterostructures
Chirag Chandrakant Palekar, Joakim Hagel, Barbara Rosa +7
Van der Waals heterostructures based on TMDC semiconducting materials have emerged as promising materials due to their spin-valley properties efficiently contrived by the stacking-…
Perfect Coulomb drag and exciton transport in an excitonic insulator
Ruishi Qi, Andrew Y. Joe, Zuocheng Zhang +8
Strongly coupled two-dimensional electron-hole bilayers can give rise to novel quantum Bosonic states: electrons and holes in electrically isolated layers can pair into interlayer…
Valley-polarized Exitonic Mott Insulator in WS2/WSe2 Moiré Superlattice
Zhen Lian, Yuze Meng, Lei Ma +14
Strongly enhanced electron-electron interaction in semiconducting moiré superlattices formed by transition metal dichalcogenides (TMDCs) heterobilayers has led to a plethora of int…
Exciton Superposition across Moiré States in a Semiconducting Moiré Superlattice
Zhen Lian, Dongxue Chen, Yuze Meng +9
Moiré superlattices of semiconducting transition metal dichalcogenides (TMDCs) enable unprecedented spatial control of electron wavefunctions in an artificial lattice with periodic…
