NUMERICAL INVESTIGATION OF ONE-DIMENSIONAL TUNNEL JUNCTION ARRAYS AT TEMPERATURES ABOVE THE COULOMB-BLOCKADE REGIME

Arrays of tunnel junctions provide simple thermometric parameters in t he limit where thermal excitations dominate over charging effects. We present numerical simulations for calculating the current versus volta ge characteristics of an arbitrary one-dimensional array at arbitrary temperatures on the premise of the ''orthodox theory.'' The purpose of the computer simulations is to investigate the suitability of tunnel junction arrays for thermometry at low temperatures when the analytica l formulas do not hold and, specifically, to see the effect of backgro und charges in this regime.
