Popis: In this chapter, the systematic evolution with doping of the normal state properties (resistivity and Hall effect) of the La2 − xSrxCuO4 thin film cuprates is analyzed. This analysis reveals convincing evidence in favor of the presence of the charge-rich 1D features (stripes), which eventually determine the 1D character of the transport properties at temperatures below the so-called ‘spin-gap’ temperature T*(x). Measurements of the fluctuation conductivity show how stripe coupling close to Tc recovers the 2D character of the Cu-O planes which is responsible for the 2D Aslamasov–Larkin fluctuations at T~Tc and the superconducting state itself at T
