Layer-parity-dependent interfacial coupling in NbCl/graphene van der Waals heterostructures
Hansheng Xu, Yuchen Gao, Xinyue Huang +8
Strongly correlated two-dimensional systems provide compelling platforms for investigating exotic quantum phenomena. Niobium chloride (NbCl), a single-band Mott insulator,…
Layer-parity-defined surface polarization in NbCl for excitonic modulation at van der Waals interfaces
Xinyue Huang, Hansheng Xu, Yuchen Gao +10
The intrinsic symmetry breaking in the breathing kagome lattice of layered NbCl provides a unique mechanism for realizing electrically polar surfaces. In each monolayer, th…
Designer Heavy Fermions in Incommensurate /Graphene van der Waals Heterostructures
Yuchen Gao, Wenjie Zhou, Fan Yang +7
Heavy fermion systems, traditionally realized in rare-earth compounds with limited tunability, have hindered systematic exploration of correlated quantum phenomena. Here, we introd…
Polarized electroluminescence with magnetic spectral tuning in van der Waals magnet CrSBr
Yilei Wang, Shiqi Yang, Leyan Huang +7
Polarized wavelength-tunable electroluminescence (EL) represents a critical on-demand functionality for next-generation optoelectronics. While conventional van der Waals (vdW) EL d…
Intrinsic localized excitons in MoSe/CrSBr heterostructures
Xinyue Huang, Zhigang Song, Yuchen Gao +6
We present a comprehensive investigation of optical properties in MoSe/CrSBr heterostructures, unveiling the presence of localized excitons represented by a new emission featur…
