Figure 5.14: Current-voltage characteristics of PDEG-1, PTEG-1, and PTeEG-1 doped with n-DMBI, before (solid lines) and after (dashed lines) the application of a long duration bias voltage stress. n-DMBI doped PTeEG-1, which undergoes a substantial ionic drift under the bias voltage stress, shows a super linear I-V curve after the removal of the bias, as discussed in chapter 4.
