Chuan Li,Jorrit Cornelis de Boer,Bob de Ronde,S. V. Ramankutty,Erik van Heumen,Yingkai Huang,Anne de Visser,Alexander A. Golubov,Alexander A. Golubov,Mark S. Golden,Alexander Brinkman +10 more
TL;DR: N nanoscale phase-sensitive junction technology is utilized to induce superconductivity in the Dirac semimetal Bi1−xSbx via the proximity effect and shows that a magnetic field applied in the plane of the junction allows tuning of the Josephson junctions from 0 to π regimes.
$4\pi$ periodic Andreev bound states in a Dirac semimetal
Chuan Li,Jorrit Cornelis de Boer,Bob de Ronde,S. V. Ramankutty,Erik van Heumen,Yingkai Huang,Anne de Visser,Alexander A. Golubov,Mark S. Golden,Alexander Brinkman +9 more
TL;DR: In this paper, phase-sensitive junction technology is used to induce superconductivity in a Dirac semimetal and radio frequency irradiation experiments reveal a significant contribution of 4$\pi$-periodic Andreev bound states to the supercurrent in Nb-Bi${0.97}$Sb$_{0.03}$-Nb Josephson junctions.
