Kiesslich, G and Sprekeler, H and Wacker, A and Schoell, E (2003) Positive Correlations in Tunneling through coupled Quantum Dots. Semicond. Sci. Technol., 19. S37-.Full text not available from this repository.
Due to the Fermi-Dirac statistics of electrons the temporal correlations of tunneling events in a double barrier setup are typically negative. Here, we investigate the shot noise behavior of a system of two capacitively coupled quantum dot states by means of a Master equation model. In an asymmetric setup positive correlations in the tunneling current can arise due to the bunching of tunneling events. The underlying mechanism will be discussed in detail in terms of the current-current correlation function and the frequency-dependent Fano factor.
