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…
Building 3D superconductor-based Josephson junctions using a via transfer approach
Cequn Li, Le Yi, Kalana D. Halanayake +8
The coupling of superconductivity to unconventional materials may lead to novel quantum states and potential applications. Controlling the quality of the superconductor-normal meta…
Proximity-Induced Superconductivity in Epitaxial Topological Insulator/Graphene/Gallium Heterostructures
Cequn Li, Yi-Fan Zhao, Alexander Vera +16
The introduction of superconductivity to the Dirac surface states of a topological insulator leads to a topological superconductor, which may support topological quantum computing…
Tunable Two-Dimensional Group-III Metal Alloys
Siavash Rajabpour, Alexander Vera, Wen He +20
Chemically stable quantum-confined 2D metals are of interest in next-generation nanoscale quantum devices. Bottom-up design and synthesis of such metals could enable the creation o…
Rules for Phase Shifts of Quantum Oscillations in Topological Nodal-line Semimetals
Cequn Li, C. M. Wang, Bo Wan +3
Nodal-line semimetals are topological semimetals in which band touchings form nodal lines or rings. Around a loop that encloses a nodal line, an electron can accumulate a nontrivia…
Surface Reactivity Enhancement by O2 Dissociation on a Single-layer MgO Film Deposited on Metal Substrate
Cequn Li, Jing Fan, Bin Xu +1
Improving reactivity on an insulating surface is crucial due to their important applications in surface catalytic reactions. In this work, we carried out first-principles calculati…
