Abstract:
A combination of electrode grid and organic top-surface coating overlying said electrode grid, comprising:a substrate;a plurality of electrodes formed on said substrate; andan organic top-surface coating overlaying said electrodes and said substrates comprising:a polymer selected from the group consisting of polycarbonate, polyvinylcarbazole, or cellulose acetate butyrate;a charge transport agent selected from the group consisting of m-TBD, P-TBD, TM-TBD, or dihydroxy m-TBD; anda solvent, wherein said solvent is a solution comprising methylene chloride and 1,1,2-trichloroethane;wherein said coating has a time constant, a dielectric constant, and a resistivity, said time constant, determined by a product of the dielectric constant and the resistivity of the material, being between 1 microsecond and 1 second, said dielectric constant being between 4 and 12, and said resistivity being between 1.times.10.sup.10 and 1.times.10.sup.11 ohm-centimeters.
