Abstract
We present millikelvin studies of magnetoresistance for epitaxial film s and wires of CdTe:In. In comparison to the data, with theoretical pr edictions for the weakly localized regime we put into the evidence the presence of the temperature-induced dimensional crossovers in the stu died systems. Our measurements probe the electron phase-breaking rate and indicate that the main dephasing mechanism arises from electron sc attering from thermal fluctuations of three- or two-dimensional electr on liquid.
