Oxygen-Dependent Instability and Annealing/Passivation Effects in Amorphous In-Ga-Zn-O Thin-Film Transistors

This letter discusses the reason for the instability of amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs) under both positive and negative bias stresses. This instability is significantly influenced by the oxygen content in the bulk IGZO and the surrounding environment. The a...
