Abstract (English)

In this thesis, we investigate electronic transport through molecular quantum dots weakly coupled to source and drain leads. To describe the electronic spectrum of the molecule that forms the quantum dot, the Pariser-Parr-Pople Hamiltonian for conjugated molecules is introduced and adapted to the case of a benzene molecule. The generalized master equation (GME), which is the equation of motion ...

Translation of the abstract (German)

In dieser Arbeit untersuchen wir Transport von Elektronen durch molekulare Quantenpunkte, die schwach an metallische Kontakte gekoppelt sind. Um das elektronische Spektrum des Moleküls, welches den Quantenpunkt darstellt, zu beschreiben, wird der Pariser-Parr-Pople Hamiltonoperator für konjugierte Moleküle eingeführt, und für das Benzenemoleküle adaptiert. Die verallgemeinerte Mastergleichung ...
