Electronic Reconstruction Towards Topological Superconductivity in FeTe
Hongtao Rong, Yang Ge, Zi-Jie Yan +13
The recent discovery of intrinsic superconductivity in stoichiometric FeTe films has renewed interest in the Te-rich end member of the iron chalcogenides for studies of unconventio…
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…
Enhanced Superconductivity in Multilayer FeSe Films by Simplified Molecular Beam Epitaxy
Maria Hilse, Hemian Yi, Zhe Chen +7
Multi-unit-cell (UC) \b{eta}-FeSe films grown on SrTiO3(100) continue to attract attention because of the significant enhancement in the superconducting transition temperature (Tc)…
Interface-Confined Superconductivity with Thickness-Independent Superfluid Stiffness in (Pb,Sn)Te/FeTe Bilayers
Zi-Jie Yan, Hongtao Rong, Yiyuan Luo +12
Interface-induced superconductivity in FeTe-based heterostructures provides a promising route toward topological superconductivity, yet the roles of the neighboring layers topology…
Coexistence of Superconductivity and Antiferromagnetism in Topological Magnet MnBi2Te4 Films
Wei Yuan, Zi-Jie Yan, Hemian Yi +15
The interface of two materials can harbor unexpected emergent phenomena. One example is interface-induced superconductivity. In this work, we employ molecular beam epitaxy to grow…
Crossover of Ising- to Rashba-Type Superconductivity in Epitaxial Bi2Se3/Monolayer NbSe2 Heterostructures
Hemian Yi, Lun-Hui Hu, Yuanxi Wang +15
A topological insulator (TI) interfaced with an s-wave superconductor has been predicted to host an unusual form of superconductivity known as topological superconductivity (TSC).…
