Abstract (English)

Which mechanisms rule the current flow across a nanostructure? We address in this thesis two aspects concerning this question. At first, we deal with a theory of electron transfer through a quantum system weakly coupled to metallic leads. The charge carriers can only be exchanged by tunnelling processes. Although the tunnelling probability decreases with the number of simultaneously tunnelling ...

Welche Mechanismen liegen dem Stromfluss über Nanostrukturen zugrunde? Wir widmen uns in diesem Werk zwei Aspekten dieser Fragestellung. Zunächst betrachten wir eine Theorie des Elektronentransfers durch ein Quantensystem mit schwach angekoppelten metallischen Zuleitungen. Die Ladungsträger können nur durch Tunnelprozesse übertragen werden. Zwar sinkt die Tunnelwahrscheinlichkeit mit der Anzahl ...
