We subjected OTFTs to electrical stress under various illumination conditions, in the visible-light range. Negligible intrinsic degradation is observed without stress and light permanent effects of light without stress on OTFT properties are very modest. When light and stress are applied simultaneously, the degradation is much stronger, than stress alone. We found that the acceleration factor is over 2 if blue light is shed on the devices.

Abstract
We subjected OTFTs to electrical stress under various illumination conditions, in the visible-light range. Negligible intrinsic degradation is observed without stress and light permanent effects of light without stress on OTFT properties are very modest. When light and stress are applied simultaneously, the degradation is much stronger, than stress alone. We found that the acceleration factor is over 2 if blue light is shed on the devices.File in questo prodotto:
