Abstract

This chapter gives an experimental observation on the transport properties of long GaAs quantum wires. The transport properties of a wire strongly depend on temperature and wire length. Due to interactions between electrons, the conductance is predicted to decrease with temperature, as predicted by the Luttinger liquid model, with power-law dependences obtained in the limits of both weak and strong scatterers. Moreover, localization effects, as predicted by the many impurities theory, are expected to be relevant for wires containing a larger number of impurities or only at sufficiently low temperatures, even for macroscopically long wires.
