Signatures of nodal superconductivity in stoichiometric FeTe
Cequn Li, Zi-Jie Yan, Yang Ge +13
Superconductivity in stoichiometric FeTe opens access to the FeTe endpoint of the Fe(Se,Te) phase diagram, yet the nature of its superconducting pairing state remains unresolved. I…
Competing Chern states revealed by quasiparticle charging in moiré rhombohedral graphene
Hongyuan Li, Zuhan Geng, Junseok Seo +13
Moiré materials realize a versatile platform for exploring the physics of fractional Chern insulators (FCIs). The recently observed evolution from FCIs to an extended quantum anoma…
Nonvolatile Switching of Magnetism via Gate-Induced Sliding in Tetralayer Graphene
Daniel Brandon, Tixuan Tan, Yiwen Ai +7
Interlayer sliding degrees of freedom often determine the physical properties of two-dimensional (2D) materials. In graphene, for instance, the metastable rhombohedral stacking arr…
Gate-tunable electroresistance in a sliding ferroelectric tunnel junction
Bozo Vareskic, Finn G. Kennedy, Takashi Taniguchi +3
We fabricate and measure electrically-gated tunnel junctions in which the insulating barrier is a sliding van der Waals ferroelectric made from parallel-stacked bilayer hexagonal b…
Band structure engineering using a moiré polar substrate
Xirui Wang, Cheng Xu, Samuel Aronson +11
Applying long wavelength periodic potentials on quantum materials has recently been demonstrated to be a promising pathway for engineering novel quantum phases of matter. Here, we…
