Zusammenfassung: | We present a complete numerical calculation and an experimental data analysis of the universal conductance fluctuations in quasi-one-dimensional nanowires. The conductance peak density model, introduced in nanodevice research by Ramos et al. [Phys. Rev. Lett. 107, 176807 (2011)], is applied successfully to obtain the coherence length of InAs nanowire magnetoconductance and we prove its equivalence with correlation methods. We show the efficiency of the method and therefore a prominent alternative to obtain the phase-coherence length. The peak density model can be similarly applied to spintronic setups, graphene, and topological isolators where phase-coherence length is a relevant experimental parameter. |
