【 摘 要 】

A current due to a tunneling event that involves three times the charge of an electron was observed in the current-voltage characteristics of a superconducting single-electron tunneling transistor. Ln this tunnel event, a Cooper pair tunnels through one tunnel barrier simultaneously with a quasiparticle that tunnels through a second tunnel barrier which is about 0.5 mu m distant from the first tunnel barrier. This current was observed in a bias regime where current flow due to sequential quasiparticle tunneling is forbidden due to the Coulomb blockade. [S0163-1829(98)01347-2].
