In this letter, we report solution-processed, high-performance Indium-Zinc-Oxide (IZO) thin-film transistors (TFTs). The annealing temperature of IZO films are studied and found that devices annealed at 350 °C exhibit the best performance. With the use of a thin Al x O y layer as the gate dielectric...
