چکیده
Abstract We report on the fabrication of Josephson junction devices with weak links utilizing Weyl and higher-order topological semimetal WTe 2 . show that /Pd contact annealed at a low temperature 80 °C did not exhibit superconducting properties because neither nor Pd are superconductors in ground state. Upon 180 annealing, spontaneous formation PdTe due to diffusion enabled us obtain interface between superconductor suitable for junction. This result is facile technique make induce Cooper pairs into telluride semimetals.

Theory of the Josephson effect in superconductor / ferromagnet / superconductor junctions
To reveal the influence of the exchange interaction on the Josephson effect, the d.c. Josephson current in unconventional-superconductor / ferromagnet / unconventional-superconductor junctions is studied. When the two superconductors have d-wave symmetry, the Josephson current is drastically suppressed with the increase of the exchange interaction. On the other hand, when the two superconductor...
متن کاملLarge Tunable Thermophase in Superconductor – Quantum Dot – Superconductor Josephson Junctions
In spite of extended efforts, detecting thermoelectric effects in superconductors has proven to be a challenging task, due to the inherent superconducting particle-hole symmetry. Here we present a theoretical study of an experimentally attainable Superconductor - Quantum Dot - Superconductor (SC-QD-SC) Josephson Junction. Using Keldysh Green's functions we derive the exact thermo-phase and ther...
متن کامل0-pi transition in magnetic triplet superconductor josephson junctions.
We examine a Josephson junction involving two arbitrary equal-spin-pairing unitary triplet superconductors and a ferromagnetic tunneling barrier. Using perturbation theory, we show how the interaction of the barrier moment with the spin of the tunneling triplet Cooper pairs can reverse the sign of the Josephson charge current. This also results in a Josephson spin current, which contains a phas...
متن کاملOptimization of a Josephson voltage array based on frequency dependently damped superconductor–insulator–superconductor junctions
We have developed a programmable Josephson voltage standard based on an array of superconductor–insulator–superconductor junctions. The junctions are damped by an external frequency-dependent shunt circuit, which allows operation at Shapiro steps with n.1. We derive optimization criteria for the design parameters for a fast and stable array with low power consumption. An array able to generate ...
متن کاملNew type of Weyl semimetal with quadratic double Weyl fermions.
Weyl semimetals have attracted worldwide attention due to their wide range of exotic properties predicted in theories. The experimental realization had remained elusive for a long time despite much effort. Very recently, the first Weyl semimetal has been discovered in an inversion-breaking, stoichiometric solid TaAs. So far, the TaAs class remains the only Weyl semimetal available in real mater...
