The so called phase-coherence lengthand its relation to the geometrical dimensions of a sample determine the electronic transport regime. Different approaches are established for extractingfrom magnetotransport data of mesoscopic systems and need to be cross-checked by using experimental data on the same model system in order to ensure an overall consistent theoretical description. Suitable model systems for testing this consistency are single GaN:Ge nanowires. Their magnetoconductance at low temperatures exhibits universal conductance fluctuations as well as weak localization effects. We find that the values ofobtained from the established analysis of the magnitude of the conductance fluctuations rms() decrease with increasing measurement current, whereas the corresponding values ofdetermined by the analyses of the correlation fieldand the weak localization effect yield the same value forindependent of the measurement current used. We apply and modify the existing theoretical framework for bias-dependent differential conductance fluctuations, in order to explain the decrease of the conductance fluctuations rms() with increasing current density in our dc measurements. This leads to the same values ofindependent of the analysis approach applied to the same set of data.
