Effect of network topology on nanocluster film transport
The effects of network topology on electron transport is studied using Monte Carlo simulations of tunnel junction networks with transport governed by Coulomb blockade. Both the threshold voltage shift and the nonlinearity of the I-V curves are sensitive to lateral fluctuations of the conduction paths due to random voids. The nonlinearity is found to be maximized for aspect ratios of the network of unity or larger and for random void networks with 50% horizontal connections. Comparisons are made with Au nanocluster I-V measurements.
