A novel process for the formation of thin-film, optical-quality conductive electrodes for use in electrophoretic deposition of high-resolution phosphor screens is described. The thin-film metal electrodes can be removed from under the phosphor either chemically or by vacuum sublimation leaving a completely transparent interface. The metal electrodes show good adherence to substrates and are low in pinhole density. High condensation rates are obtained through the use of nucleation techniques. 相似文献

We characterize thin films of a new conductive copolymer, sulfonated poly(thiophene-3-[2-(2-methoxyethoxy)ethoxy]-2,5-diyl) (S-P3MEET), with various chemical additives to determine if the films are suitable for use as a hole transport layer in organic electronic devices. Using atomic force microscopy, Kelvin probe, and contact angle measurements, we probe the surface morphology and composition of S-P3MEET thin films. We then use DC conductivity measurements and spectroscopic ellipsometry to determine how the additives change the bulk properties of the films. We find that the additives decrease conductivity, increase work function, and alter the complex refractive index. The resulting properties make some preparations of S-P3MEET advantageous for use in light emitting diodes. 相似文献
