Abstract

We study a bilinear array of normal tunnel junctions in order to theoretically investigate the nature of correlations in space and time of the current. The bilinear array consists of two parallel rows of tunnel junctions which are capacitively coupled in either a straight or slanted coupling configuration. We use the kinetic Monte Carlo algorithm to simulate the time evolution of the array. We show that while slanted coupling modifies the correlated transport behaviour within the array compared to straight coupling, both circuit topologies show instability of the charge distribution during the conducting state.
