The steady-state current-voltage characteristics resulting from charge injection from a metal into an organic charge transporting polymer are found to deviate significantly from the space-charge-limited values when a Langmuir–Blodgett film of cadmium stearate is interposed between the metal and the organic polymer. A phenomenological model of charge injection is proposed to account for the observed features, and to quantify the injection level of a non-Ohmic contact.

    A new type of coating involving a layer-by-layer technique has been recently reported. This coating is composed of a polyelectrolyte multilayer film that confers specific properties on surfaces to which it is applied. Here, we studied the applicability of such a technique to the coating of oral...
