Dimensional disordered lattice

The calculation of particular cases of two levels and uniform distributions of site and transition energies shows the applicability of the constructed expressions not only for site disorder system, but also for mixed system with both site and transition disorders. The blocking effect is studied and also discussed.

In many-particle case, the blocking effect results in decreasing correlation factor F and average time τjump between two consecutive jumps. With increasing the number of particles, the diffusion coefficient DM decreases for site-energy and transition-energy disordered lattices due to the F-effect affects stronger than τ -effect. Furthermore, the blocking effect almost is temperature independent for both lattices.
