Abstract
In a previous report [Phys. Lett. A 216, 178 (1996)] we phenomenologically considered the conduction mechanism of a highly disordered carbon system. I n this article a metal-insulator transition is investigated based on our th eory for the disordered system. Our results for the temperature-dependent c onductivity show an apparent metal-insulator transition and are in good agr eement with experimental results in disordered carbons.
