ABSTRACT
The surface of poly (9,9-dioctylfluorene) (PFO) film was modified by 1.0 keV Ar[sup +] irradiation with a dose of 6.5x10[sup 14] ions/cm[sup 2] prior to Ca deposition. Ultraviolet and x-ray photoelectron spectroscopic studies indicated that the modified surface could effectively block Ca diffusion into the PFO film and prevent the formation of doping-induced bipolaron states in the former forbidden energy gap. As a result, a sharper metal contact on the surface of the PFO film could be formed, compared to that on the surface without Ar[sup +] irradiation. The results suggest that the judicial surface modification of polymer surfaces may be useful for the improvement of metal/polymer contacts and thus device performance. © 2000 American Institute of Physics.

    Irradiation with infrared light is found to stimulate the electrical conductivity of a film of an organic polymeric conductor [poly(3,4-ethylenedioxythiopene) with polystyrene sulfonate]. The change in conductivity is found to be linear in the intensity of the irradiation (4-400 mW/cm²). Both...
