Secondary Coulomb Blockade Gap in a Four-Island Tunnel-Junction Array
Mincheol Shin, Seongjae Lee, Kyoung Wan Park +1
In the ring-shaped tunnel-junction array with four islands, the secondary Coulomb blockade gap in a low bias-voltage range is observed in the I-V characteristics. We attribute its…

Geometrically Induced Multiple Coulomb Blockade Gaps
Mincheol Shin, Seongjae Lee, Kyoung Wan Park +1
We have theoretically investigated the transport properties of a ring-shaped array of small tunnel junctions, which is weakly coupled to the drain electrode. We have found that the…
