A Unified Degradation Model of a-InGaZnO TFTs Under Negative Gate Bias With or Without an Illumination

Degradation behaviors of amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs) under negative bias stress (NBS) and negative bias illumination stress (NBIS) are investigated systematically. In some cases, a two-stage degradation behavior of a-IGZO TFTs is observed under both NBS...
