Özet

We have studied the electronic mobility mu within the completely disordered lattice model by using a strong interatomic hopping V(r) = -(a(H)/r)exp(-r/a(H)) in site representation of the Hamiltonian. Considered as a function of the disorder parameter x = a(H)/a, with a(H) the Bohr radius and a mean atomic distance, it is found that mu decreases with increasing x or increasing material density rho.
