dc.descriptionWe have theoretically investigated the time-evolution of electron transport from a two-dimensional electron system (2DES) to a quantum dot (QD). We clearly showed that the coherent electron transport is remarkably modified depending on the initial electronic state in the 2DES. The electron transport from the 2DES to the QD is strongly enhanced when the initial state of electron in the 2DES is localized below the QD. We indicate that these features should be obtained in other nano-structure-electrode coupled systems, and the electron transport between the systems having completely different geometrical conditions is significantly affected by the initial spatial distribution of the electron density.
