      abstract     = {Low-temperature transport in nanowires is accompanied by
                      phase-coherent effects, which are observed as modulation of
                      the conductance in an external magnetic field. In the
                      GaAs/InAs core/shell nanowires investigated here, these are
                      h/e flux periodic oscillations in a magnetic field aligned
                      parallel to the nanowire axis and aperiodic universal
                      conductance fluctuations in a field aligned perpendicularly
                      to the nanowire axis. Both electron interference effects are
                      used to analyse the phase coherence of the system.
                      Temperature-dependent measurements are carried out, in order
                      to derive the phase coherence lengths in the cross-sectional
                      plane as well as along the nanowire sidewalls. It is found
                      that these values show a strong anisotropy, which can be
                      explained by the crystal structure of the GaAs/InAs
                      core/shell nanowire. For nanowires with a radius as low as
                      45 nm, flux periodic oscillations were observed up to a
                      temperature of 55 K.},
