Abstract
Electron packet transport through two nodes built between three multiple-tunnel junctions (MTJs) was investigated. Two trapezoidal voltage pulses were applied to each node to transfer the electron packet. A pump current due to sequential transport of the electron packets was observed at a particular phase delay where the backward tail of the first pulse just overlapped the forward tail of the second pulse, whereas synchronized pulses could not carry the current. A dependence on pulse shape was also investigated.Keywords
