abstract = {The study of the transport properties of quasi
one-dimensional topological insulator (TI)
nanostructuresunder the application of an in-plane magnetic
field is crucial for the later realization oftopological
quantum computation building blocks. We present low
temperature measurements ofselectively grown TI-Kinks under
the application of an in-plane magnetic field. A dependence
of theTI-Kink’s resistance on the angle of the in-plane
magnetic field is visible in the magnetotransportdata
resulting in a π-periodic change of the conductance. This
phenomenon originates from anorbital effect, leading to a
alignment or misalignment of the phase-coherent states on
the bottom andtop surface of the topological insulator.
Respectively, the aligned and misaligned states leadto a
increased or decreased conductance in the device. The
measurement results are supportedtheoretically by the
analysis of a surface Rashba-Dirac model and tight-binding
simulations of aneffective 3-dimensional mode},
