Using Monte Carlo simulation, we studied the electrical conductivity of two-dimensional
films. The films consisted of a poorly conductive host matrix and highly conductive rod-like
fillers (rods). The rods were of various lengths fitting a log-normal distribution. They could be
aligned along a direction. Special attention was paid to films having completely aligned
rods. The impact of length dispersity and the extent of rod alignment on the insulator-to-
conductor phase transition were studied. The greater the length dispersity the smaller the …
