Abstract (English)

In this thesis we consider the vibrational effects on the electric transport properties of a quantum dot system. We thereby address three different problems. In the first part, we develope a theoretical model of a single level quantum dot system which is coupled to many vibronic modes. According to this model, many vibronic degenerate state can contribute to transport at finite bias. However, ...

Die vorliegende Arbeit untersucht den Einfluss von Schwingungsanregungen auf die elektrischen Transporteigenschaften eines Quantenpunktsystems. Wir widmen uns dabei drei verschiedenen Problemen. Im ersten Teil der Arbeit wird ein theoretisches Modell eines Einniveau-Quantenpunktes entwickelt, der an eine große Zahl von Schwingungsanregungen koppelt. Gemäß diesem Modell können bei endlicher ...
