Strongly Enhanced Charge-Density Waves and Correlated Insulating State in Atomically Thin 1-TaS
Gan Liu, Yulu Liu, Qiling Luo +7
We investigate thickness-dependent charge-density-wave (CDW) transitions in 1-TaS using temperature-dependent Raman spectroscopy and electrical transport. Raman measurements…
Hidden valley dynamics behind vanishing circular polarization in moiré excitons
Yuto Urano, Lata Chouhan, Nurul Fariha Ahmad +4
Optically addressable valley degrees of freedom in transition-metal dichalcogenide heterostructures provide a powerful platform for valleytronic and quantum-optical functionalities…
Observation of a Mott quantum spin Hall insulator in twisted WSe2
Yifei Jin, Yaqi Ma, Aoqian Zhang +9
Quantum spin Hall (QSH) insulators and Mott insulators are conventionally regarded as distinct insulating phases, arising from band topology and strong Coulomb interactions, respec…
Mechanochemical Nano-Writing of an Atomically Thin Metal
Shuai Zhang, Yanyu Jia, Atanu Samanta +14
Mechanical energy accelerates many physicochemical processes, including materials syntheses that are hard to produce with thermal energy alone. However, physical understanding conn…
Ferroelectric-tunable quantum nonlinearity of chiral Bloch electrons in a moiré system
Zitian Pan, Jundong Zhu, Yu Hong +7
Sliding ferroelectricity in van der Waals materials shows great potential for designing robust memory devices. However, its thermodynamic behaviors and the coupling with certain qu…
Tailoring pure valley-Zeeman spin-orbit coupling in WSe-encapsulated monolayer graphene
Yaqing Han, Siqi Jiang, Jingkuan Xiao +17
Engineering proximity effects in twisted van der Waals heterostructures offers a powerful platform for designing electronic properties. While theoretical predictions of quantum int…
