Unconventional Josephson effect in hybrid superconductor-topological insulator devices.
نویسندگان
چکیده
We report on transport properties of Josephson junctions in hybrid superconducting-topological insulator devices, which show two striking departures from the common Josephson junction behavior: a characteristic energy that scales inversely with the width of the junction, and a low characteristic magnetic field for suppressing supercurrent. To explain these effects, we propose a phenomenological model which expands on the existing theory for topological insulator Josephson junctions.

متن کاملAn Extraordinary Josephson Junction
The combination of symmetry breaking effects, such as those occurring in magnets and superconductors, with topological order may result in remarkable new physics. Recent theoretical studies suggest that, in certain superconductors, exotic quasiparticle excitations can emerge that behave like Majorana fermions, chargeneutral quasiparticles that are their own antiparticles. In Physical Review Let...
متن کاملGeometric dependence of Nb-Bi2Te3-Nb topological Josephson junction transport parameters
Superconductor-topological insulator–superconductor Josephson junctions have been fabricated in order to study the width dependence of the critical current, normal state resistance and flux periodicity of the critical current modulation in an external field. Previous literature reports suggest anomalous scaling in topological junctions due to the presence of Majorana bound states. However, for ...
متن کاملJosephson supercurrent through a topological insulator surface state.
The long-sought yet elusive Majorana fermion is predicted to arise from a combination of a superconductor and a topological insulator. An essential step in the hunt for this emergent particle is the unequivocal observation of supercurrent in a topological phase. Here, direct evidence for Josephson supercurrents in superconductor (Nb)-topological insulator (Bi(2)Te(3))-superconductor electron-be...
متن کاملJosephson Current and Noise at a Superconductor/Quantum-Spin-Hall-Insulator/Superconductor Junction
We study junctions between superconductors mediated by the edge states of a quantum-spin-Hall insulator. We show that such junctions exhibit a fractional Josephson effect, in which the current phase relation has a 4π rather than a 2π periodicity. This effect is a consequence of the conservation of fermion parity—the number of electron mod 2—in a superconducting junction and is closely related t...
