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…
Evidence of Mott Insulator with Thermally Induced Melting Behavior in Kagome Compound Nb3Cl8
Qiu Yang, Min Wu, Jingyi Duan +12
The kagome lattice provides a playground to explore novel correlated quantum states due to the presence of flat bands in its electronic structure. Recently discovered layered kagom…
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…
