High-Tc superconductor Fe(Se,Te)monolayer:an intrinsic,scalable and electrically tunable Majorana platform
文献摘要：
Iron-based superconductors have been identified as a novel platform for realizing Majorana zero modes(MZMs)without heterostructures,due to their intrinsic topological properties and high-Tc superconductivity.In the two-dimensional limit,the FeTe1-xSex monolayer,a topological band inversion has recently been experimentally observed.Here,we propose to create MZMs by applying an in-plane magnetic field to the FeTe1-xSex monolayer and tuning the local chemical potential via electric gating.Owing to the anisotropic magnetic couplings on edges,an in-plane magnetic field drives the system into an intrinsic high-order topological superconductor phase with Majorana corner modes.Furthermore,MZMs can occur at the domain wall of chemical potentials at either one edge or certain type of tri-junction in the two-dimensional bulk.Our study not only reveals the FeTe1-xSex monolayer as a promising Majorana platform with scalability and electrical tunability and within reach of contemporary experimental capability,but also provides a general principle to search for realistic realization of high-order topological superconductivity.
