In a paper published in Nature Physics, scientists at the Max Planck Institute of Microstructure Physics, Halle show that a lateral Josephson junction made from a type-II Dirac semimetal Nickel di-telluride (NiTe2) and superconducting Niobium (Nb) electrodes exhibits a large nonreciprocal critical current such that a non-dissipative supercurrent flows in the "forward" direction but a normal dissipative current flows in the "backward" direction.
