      abstract     = {Germanium-Tin (GeSn) is a novel semiconductor Group IV
                      alloy that can be tuned from indirect to direct bandgap
                      semiconductors by adjusting the Sn content. This property
                      makes this alloy class attractive for integrated photonic
                      applications and high-mobility electronic devices. In this
                      work, the GeSn alloy properties are investigated in the view
                      of applications fields such as spintronics and quantum
                      computing. Using low-temperature magneto-transport
                      measurements, electron interference effects and deriving
                      typical mesoscopic benchmark parameters such as the
                      phase-coherence length in GeSn-based Hall bar structures for
                      Sn concentrations up to 14 $at.\%$ is investigated.
                      Furthermore, Shubnikov–de Haas oscillations provide direct
                      access to the effective mass of the Γ-valley electrons as
                      well as the charge carrier mobility. This work provides a
                      new insight into advanced group IV alloys desired for the
                      study of spin dynamics and its quantum computing
                      applications.},
