Abstract
A physical model of the metallic-type conductivity at the interface between an organic semiconductor or dielectric and a metals or another organic material is proposed. The conductivity arises due to the formation of geminal pairs with a rather high surface density at the interface. Conditions under which the transitions between molecules require neither thermal activation nor tunneling for a significant fraction of charge carriers are determined. The values of electric conductivity and carrier mobility are estimated using numerical modeling.
