Abstract

In the last ten years the progresses of microtechnology has opened the field of meso-scopic systems, where quantum information is not lost at low temperature during the travel of electrons through the sample. Beside the weak localization (WL) phenomena, that has become the appropriate tool to determine the scale of inelastic processes in macroscopic systems, mesoscopic samples exhibit a very unusual phenomena: the complex interference pattern resulting from the diffusive motion of electrons results in a very complicated but reproducible magnetoconductance curve (MC curve), which is sensitive to any microscopic disorder configuration change. The MC curve contains so a very large amount of informations but it obeys to universal statistical rules, as predicted by Universal Conductance Fluctuations (UCF) theory.
