FIG. 1.

Diagram of dot energy regimes. (a) No transport channels in the bias window, (b) single transport channel in the bias window, and (c) two transport channels and in the bias window.

FIG. 2.

Coulomb diamond detail showing suppression of ground-state current. The current increases along (i) but may decrease along (ii). In extreme cases, the decrease along (ii) matches the increase along (i), yielding no current along (iii). and correspond, respectively, to Figs. 1(b) and 1(c), and their analytic expressions are given in Eqs. (12) and (14), respectively.

FIG. 3.

Configurations capable of quenching ground-state transport. Rates involving states and involve tunneling of an electron into a dot edge state (more probable) while those involving states and involve tunneling into a dot core state (less probable).
