Probing level renormalization by sequential transport through double quantum dots
B Wunsch, M Braun, J König, D Pfannkuche - Physical Review B—Condensed …, 2005 - APS
We study electron transport through double quantum dots in series. The tunnel coupling of
the discrete dot levels to external leads causes a shift of their energy. This energy …
