Revealing Intrinsic Superconductivity of the Nb/BiSbTe <sub>2</sub> Se Interface

چکیده
Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top insulator (TI) surface. Here we observed and analyzed the double critical current in Josephson junctions based fabricated planar Superconducting Quantum Interference Device. By measuring currents as function temperature magnetic field, show that second stems from intrinsic S/TI interface, which supported modified Resistively Shunted Junction model Transmission Electron Microscopy studies. This complex structure interface should be taken into account when technological process involves Ar-plasma cleaning.

Interface high-temperature superconductivity
Cuprate high-temperature superconductors consist of two quasi-two-dimensional (2D) substructures: CuO2 superconducting layers and charge reservoir layers. The superconductivity is realized by charge transfer from the charge reservoir layers into the superconducting layers without chemical dopants and defects being introduced into the latter, similar to modulationdoping in the semiconductor supe...

متن کاملThe intrinsic heterogeneity of superconductivity in the cuprates
In the hole-doped, high-temperature superconducting cuprates, an intrinsic heterogeneity is found, from the early observations to recent data. Below optimum doping, the heterogeneity consists of dynamic metallic and, at low temperatures, superconducting regions in the form of clusters or stripes, which develop and decay as a function of time and location in the antiferromagnetic lattice. This b...
متن کاملRevealing topological superconductivity in extended quantum spin Hall Josephson junctions.
Quantum spin Hall-superconductor hybrids are promising sources of topological superconductivity and Majorana modes, particularly given recent progress on HgTe and InAs/GaSb. We propose a new method of revealing topological superconductivity in extended quantum spin Hall Josephson junctions supporting "fractional Josephson currents." Specifically, we show that as one threads magnetic flux betwee...
متن کاملInsights from the study of high-temperature interface superconductivity.
A brief overview is given of the studies of high-temperature interface superconductivity based on atomic-layer-by-layer molecular beam epitaxy (ALL-MBE). A number of difficult materials science and physics questions have been tackled, frequently at the expense of some technical tour de force, and sometimes even by introducing new techniques. ALL-MBE is especially suitable to address questions r...
