This dataset comprises experimental results on electron transport in one-dimensional quantum wires. The results demonstrate the effects of disorder and interactions within one-dimensional channels formed in GaAs-based heterostructures. The data represent two-terminal differential conductance measurements, obtained using lock-in amplifiers. All measurements were conducted in a cryogen-free dilution refrigerator at a base temperature of 45 mK. The data present differential conductance as a function of split gate voltage at various top gate voltages, both with and without a fixed magnetic field of 10 Tesla. Additionally, the dataset includes differential conductance as a function of split gate voltage, measured with a DC source-drain bias to investigate subband spacing.The dataset included here forms part of the research work published in Physical Review B, as below.
