N2 - We used a parallel coupled vertical double quantum dot device consisting of two laterally tunnel-coupled dots and a common source and drain electrodes to study the Aharanov-Bohm (AB) effects in the vertically flowing single electron tunneling current. In the charging diagram measured at a finite source-drain voltage a bonding state as a ground state, and an antibonding state as an excited state were distinguished for the one-electron state. We observed periodic magnetic oscillations for the current through the bonding state, due to the AB effect for the two tunnel-coupled dots.
