Abstract

We study carrier scattering processes in GaAs/AlGaAs quantum wires by a correlation field analysis of the conductance fluctuations observed in their low temperature magnetoresistance. In the diffusive transport regime, the magneto-resistance at low magnetic fields shows universal conductance fluctuations (UCF) and the correlation field B_c is field independent. However, at higher fields, where the Landau level quantization is resolved, B_c is found to increase as a power law of the magnetic field. We compare our results with recent theoretical predictions for the diffusive nature and also with our own semi-classical explanations for the dynamical transport.
