abstract = {We study the impact of the direction of magnetic flux on
the electron motion in GaAs/InAs core/shell nanowires. At
small tilt angles, when the magnetic field is aligned nearly
parallel to the nanowire axis, we observe Aharonov–Bohm
type h/e flux periodic magnetoconductance oscillations.
These are attributed to transport via angular momentum
states, formed by electron waves within the InAs shell. With
increasing tilt of the nanowire in the magnetic field, the
flux periodic magnetoconductance oscillations disappear.
Universal conductance fluctuations are observed for all tilt
angles, however with increasing amplitudes for large tilt
angles. We record this evolution of the electron propagation
from a circling motion around the core to a diffusive
transport through scattering loops and give explanations for
the observed different transport regimes separated by the
magnetic field orientation.},
