  The sedimentation of a two dimensional suspension containing rods was studied
by means of kinetic Monte Carlo (MC) simulations. An off-lattice model with
continuous positional and orientational degrees of freedom was considered. The
initial state before sedimentation was produced using a model of random
sequential adsorption. During such sedimentation, the rods undergo
translational and rotational Brownian motions. The MC simulations were run at
different initial number densities (the numbers of rods per unit area),
$\rho_i$, and sedimentation rates, $u$. For sediment films, the spatial
distributions of the rods, the order parameters and the electrical
conductivities were examined. Different types of sedimentation-driven
self-assembly and anisotropy of the electrical conductivity were revealed
inside the sediment films. This anisotropy can be finely regulated by changes
in the values of $\rho_i$ and $u$.
