      abstract     = {Despite the fact that GeTe is known to be a very
                      interesting material for applications in thermoelectrics and
                      for phase-change memories, the knowledge on its
                      low-temperature transport properties is only limited. We
                      report on phase-coherent phenomena in the magnetotransport
                      of GeTe nanowires. From universal conductance fluctuations
                      measured on GeTe nanowires with Au contacts, a
                      phase-coherence length of about 280 nm at 0.5 K is
                      determined. The distinct phase-coherence is confirmed by the
                      observation of Aharonov–Bohm type oscillations for
                      parallel magnetic fields. We interpret the occurrence of
                      these magnetic flux-periodic oscillations by the formation
                      of a tubular hole accumulation layer. For
                      Nb/GeTe-nanowire/Nb Josephson junctions we obtained a
                      critical current of 0.2 μA at 0.4 K. By applying a
                      perpendicular magnetic field the critical current decreases
                      monotonously with increasing field, whereas in a parallel
                      field the critical current oscillates with a period of the
                      magnetic flux quantum confirming the presence of a tubular
                      hole channel.},
