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.}, cin = {PGI-9}, ddc = {621.3}, cid = {I:(DE-Juel1)PGI-9-20110106}, pnm = {5234 - Emerging NC Architectures (POF4-523)}, pid = {G:(DE-HGF)POF4-5234}, typ = {PUB:(DE-HGF)16}, UT = {WOS:001357213800001}, doi = {10.1002/aelm.202400565}, url = {https://juser.fz-juelich.de/record/1032177}, }
