Abstract :
We subjected all-organic complementary inverters to constant voltage stress. We found a 20% maximum variation of DC inverter parameters after a 104-s stress. The largest degradation was in the delay times, which increase up to a factor 7. This is due to the threshold voltage variation in pTFTs and the mobility reduction in nTFTs.
