Abstract

We developed a method to improve the electrical performance of amorphous BaTiO3 thin film by UV-ozone treatment. The treatment promoted densification of the dielectric layer by decreasing oxygen-vacancy and increasing metal-oxide bonds. The InGaZnO-TFTs exhibited high on/off ratio of 1.46 × 107 and the low sub-threshold swing of 0.069 V/dec.
