Fig. 1. Schematic view of our experimental designs for the measurements of (a) anomalous Shapiro steps, (b) currentphase relation, and (c) zero-bias conductance peak as an evidence of Majorana fermion state in topological insulator nanowire.
Fig. 2. Current vs. voltage characteristic curve obtained from (Bi1-xSbx)2Se3 TI nanowire contacted with PbIn superconducting electrodes. The arrows indicate a hysteretic behavior. Inset: representative scanning electron microscopy image of TI nanowire-based JJ. Scale bar indicates 1 μm.
