Özet
In this work we have studied the electronic mobility m within a completely disordered lattice system by using the strong interatomic hopping potential V(r) = ( - {\frac{{r}}{{ao} }}) \exp( - r / ao ) for site representation of the Hamiltonian. It is shown that a metallic system of a completely disordered lattice first goes insulating and then goes back to metallic again at higher atomic density r .
