abstract = {We study the effects of spin-orbit coupling on the
magnetoconductivity in diffusive cylindrical semiconductor
nanowires. Following up on our former study on tubular
semiconductor nanowires, we focus in this paper on nanowire
systems where no surface accumulation layer is formed but
instead the electron wave function extends over the entire
cross section. We take into account the Dresselhaus
spin-orbit coupling resulting from a zinc-blende lattice and
the Rashba spin-orbit coupling, which is controlled by a
lateral gate electrode. The spin relaxation rate due to
Dresselhaus spin-orbit coupling is found to depend neither
on the spin density component nor on the wire growth
direction and is unaffected by the radial boundary. In
contrast, the Rashba spin relaxation rate is strongly
reduced for a wire radius that is smaller than the spin
precession length. The derived model is fitted to the data
of magnetoconductance measurements of a heavily doped
back-gated InAs nanowire and transport parameters are
extracted. At last, we compare our results to previous
theoretical and experimental studies and discuss the
occurring discrepancies.},
