      abstract     = {Ohmic contacts to GaAs/AlGaAs core/shell nanowires are
                      prepared by using a Ni/AuGe/Ni/Au layer system. In contrast
                      to Ohmic contacts to planar GaAs/AlGaAs layer systems here,
                      relatively low alloying temperatures are used in cylindrical
                      geometry. Lowest resistances are found for annealing
                      temperatures of 320 degrees C and 340 degrees C. For
                      annealing temperatures exceeding 360 degrees C, the
                      nanowires degraded completely. Nanowires annealed under
                      optimized conditions preserved their Ohmic characteristics
                      even down to temperatures of 4K. (C) 2012 American Institute
