Layer-Hybridized Wigner Crystals in MoSe2/WS2 Moiré Superlattice
Tianyi Ouyang, Yuze Meng, Li Yan +11
Transition metal dichalcogenide moiré heterobilayers with type-II band alignment provide a versatile platform for layer-polarized generalized Wigner crystals, in which strong Coul…
Propagating Collective Spin-valley Modes in Twisted WSe2
Richen Xiong, Yi Guo, Chenxin Qin +15
The emergence of neutral collective modes is a hallmark of correlated quantum phases but is often challenging to probe experimentally. In two-dimensional flatband systems, charge r…
C-band 160 Gbs-1 Zero-bias Graphene Photodetectors: Breaking the Responsivity-Bandwidth Trade-off by Heterostructure Engineering
Karuppasamy Pandian Soundarapandian, Alberto Montanaro, Ioannis Vangelidis +17
Graphene photodetectors offer ultrafast response and broadband operation, but their responsivity is typically limited by rapid hot-carrier cooling, leading to a trade-off between s…
Excitonic Mott transition without population inversion
Oleg Dogadov, Armando Genco, Allison R. Cadore +12
Exciton dissociation via the excitonic Mott transition (EMT) governs the high-density optical response of semiconductors and sets fundamental limits for optoelectronic devices. The…
Robust valley-polarized excitonic Mott states and doublons enabled by stacking-controlled moiré geometry
Hao-Tien Chu, Shou-Chien Chiu, Meng-Che Yeh +12
Atomically-thin moiré superlattices offer an optically accessible platform for interacting bosons, where strong onsite repulsion suppresses double occupancy and supports…
Robust Interlayer Exciton Interplay in Twisted van der Waals Heterotrilayer on a Broadband Bragg Reflector up to Room Temperature
Bhabani Sankar Sahoo, Shachi Machchhar, Avijit Barua +6
We report robust room temperature interlayer excitons in transition metal dichalcogenide heterostructures engineered via precise stacking orientation and twist-angle control. We in…
