Work functions for the conducting polymers are currently under further investigation. For ITO, work functions can vary as much as 4.6±0.5 eV depending on the method of preparation and state of oxidation; however, the "turn-on" voltage remains near 1.8 V for most of MEH-PPV diodes studied independent of the anode. S. A. Carter, M. Angelopoulous, P. J. Brock, J. Salem, and J. C. Scott, unpublished results. See also Ref. 13.

We note that different cathode materials (and cathode work functions) result in several order of magnitude changes in the low-voltage performance providing further evidence that the low-voltage behavior is mainly limited by the electron injection. Similar results have been found previously by H. Suzuki, Appl. Phys. Lett. 69, 1611 (1996), and references therein.
