Optical Voltage Profiling of 2D Semiconductors via Proximal Exciton Sensing
Ha-Leem Kim, Hyungbin Lim, Yuanyi Yang +6
High contact resistances in atomically thin semiconductors often mask intrinsic electrical transport properties, particularly at low carrier densities where exotic correlated state…
Contactless cavity sensing of superfluid stiffness in atomically thin 4Hb-TaS
Trevor Chistolini, Ha-Leem Kim, Qiyu Wang +13
The exceptional tunability of two-dimensional van der Waals materials offers unique opportunities for exploring novel superconducting phases. However, in such systems, the measurem…
Electrically controlled Heat Assisted Magnetic Recording in Intercalated 2D Magnets
Josue Rodriguez, Ruishi Qi, Catherine Xu +3
The ever-increasing demand for fast, reliable, and energy-efficient information storage continues to push magnetic memory technologies toward their fundamental limits. Conventional…
Tunable Interlayer Charge-transfer States in MoSe/WS Moiré Superlattices
Zheyu Lu, Jiahui Nie, Tianle Wang +15
Moiré superlattices formed by transition metal dichalcogenide (TMD) heterobilayers provide a versatile platform for studying strongly correlated electronic, excitonic, and topolog…
Observation of two-component exciton condensates in an excitonic insulator
Ruishi Qi, Qize Li, Jiahui Nie +9
Macroscopic quantum coherence emerges when bosons condense into a Bose-Einstein condensate (BEC). First observed as a single-component superfluid in helium, BECs later emerged in u…
Observation of an exciton crystal in a moiré excitonic insulator
Ruishi Qi, Qize Li, Haleem Kim +9
Strong Coulomb interactions can drive electrons to crystallize into a Wigner lattice. Achieving the bosonic analogue - a crystal of excitons - has remained elusive due to their sho…
