• We predict the appearance of a spontaneous polarization wave (SPW) of charges related to single electron tunneling in capacitor-coupled nanotunnel junction arrays, using a classical Monte Carlo simulation. When two one-dimensional (1D) nanojunction arrays including non-uniform tunnel resistances are strongly capacitor-coupled, excess electrons are accumulated in the islands, connected to the largest tunnel resistance, of one array and, hence, holes are accumulated to compensate them in the island of the other array. This leads to a SPW, synchronized with the Coulomb staircase. It is shown that the SPW is observable even at very high frequencies without a decrease of SPW amplitude, by reducing the tunnel resistances. This SPW will be useful in cell array devices utilizing single electron tunneling.
