抜粋

We report an asymmetric current blockade phenomenon which occurs in unique, hybrid vertical/lateral GaAs quantum dots and which modifies the nonlinear current-voltage characteristics. The data exhibit an enlargement of Coulomb blockade regions in the plane of source-drain and gate voltage, revealing suppression of elementary transitions between ground states or excited state of different electron number. This suppression indicates inaccessibility due to the eigenstate from the dot to 2DEG.
