Noise enhancement due to quantum coherence in coupled quantum dots

G. Kießlich, E. Schöll, T. Brandes, Frank Hohls & Rolf J. Haug
We show that the intriguing observation of noise enhancement in the charge transport through two vertically coupled quantum dots can be explained by the interplay of quantum coherence and strong Coulomb blockade. We demonstrate that this novel mechanism for super-Poissonian charge transfer is very sensitive to decoherence caused by electron-phonon scattering as inferred from the measured temperature dependence. © 2007 The American Physical Society.
