Abstract

The electron transport across metallic nanobridges at low temperatures and in good contact with electric leads is reviewed. The smallness of the samples induces two phenomena which are different from macroscopic metals. First, interference effects like universal conductance fluctuations and Aharonov-Bohm effect are observable as a result of quantum-mechanical phase coherence over the entire sample. Second, interaction effects are considered, which are induced by a reduced screening of the carrier charges. Examples for these phenomena are discussed both at zero- and finite bias voltages.
