      abstract     = {We investigated the magnetotransport of InAs nanowires
                      grown by selective-area metal-organic vapor phase epitaxy.
                      In the temperature range between 0.5 and 30 K reproducible
                      fluctuations in the conductance upon variation in the
                      magnetic field or the backgate voltage are observed, which
                      are attributed to electron interference effects in small
                      disordered conductors. From the correlation field of the
                      magnetoconductance fluctuations the phase-coherence length
                      l(phi) is determined. At the lowest temperatures l(phi) is
                      found to be at least 300 nm while for temperatures exceeding
                      2 K a monotonous decrease in l(phi) with temperature is
                      observed. A direct observation of the weak antilocalization
                      effect indicating the presence of spin-orbit coupling is
                      masked by the strong magnetoconductance fluctuations.
                      However, by averaging the magnetoconductance over a range of
                      gate voltages a clear peak in the magnetoconductance due to
                      the weak antilocalization effect was resolved. By comparison
                      of the experimental data to simulations based on a recursive
                      two-dimensional Green's-function approach a spin-orbit
                      scattering length of approximately 70 nm was extracted,
                      indicating the presence of strong spin-orbit coupling.},
