      abstract     = {Nanohybrid superconducting junctions using antimony
                      telluride (Sb2Te3) topological insulator nanoribbons and Nb
                      superconducting electrodes are fabricated using electron
                      beam lithography and magnetron sputtering. The effects of
                      bias current, temperature, and magnetic field on the
                      transport properties of the junctions in a four‐terminal
                      measurement configuration are investigated. Two features are
                      observed. First, the formation of a Josephson weak‐link
                      junction. The junction is formed by proximity‐induced
                      areas in the nanoribbon right underneath the inner Nb
                      electrodes which are connected by the few tens of nanometers
                      short Sb2Te3 bridge. At 0.5 K a critical current of 0.15 µA
                      is observed. The decrease of the supercurrent with
                      temperature is explained in the framework of a diffusive
                      junction. Furthermore, the Josephson supercurrent is found
                      to decrease monotonously with the magnetic field indicating
                      that the structure is in the small‐junction limit. As a
                      second feature, a transition is also observed in the
                      differential resistance at larger bias currents and larger
                      magnetic fields, which is attributed to the suppression of
                      the proximity‐induced superconductive state in the
                      nanoribbon area underneath the Nb electrodes.},
