Observation of Unconventional Ferroelectricity in Non-Moir'\e Graphene on Hexagonal Boron Nitride Boundaries and Interfaces
Tianyu Zhang, Yueyang Wang, Hongxia Xue +3
Interfacial interactions in two parallel-stacked hexagonal boron-nitride (hBN) layers facilitate sliding ferroelectricity, enabling novel device functionalities. Additionally, when…
Observation of Cavity-Mediated Nonlinear Landau Fan and Modified Landau Level Degeneracy in Graphene Quantum Transport
Hongxia Xue, Hsun-Chi Chan, Zuzhang Lin +9
Recent studies on cavity-coupled two-dimensional electron gas demonstrate that vacuum-field engineering can tailor electronic transport properties of materials. By achieving ultra-…
Emergence of moiré superlattice potential in graphene by twisted-hBN layers
Tianyu Zhang, Chengxin Xiao, Hongxia Xue +2
Moiré superlattices formed in stacks of two or more 2D crystals with similar lattice structures have recently become excellent platforms to reveal new physics in low-dimensional s…
Coulomb drag in graphene/hBN/graphene moiré heterostructures
Yueyang Wang, Hongxia Xue, Xiong Wang +3
We report on the observation of Coulomb drag between graphene-hexagonal boron nitride (hBN) moiré heterostructure with a moiré wavelength of 14 nm and an intrinsic graphene…
