Abstract

Because of the advantages in high mobility and low temperature process

oxide thin film transistor (TFT) becomes the hotspot in display technology at present. Gadolinium-aluminum-zinc-oxide (GdAZO) thin film and GdAZO TFT (active layer is GdAZO thin film) were fabricated. The photoluminescence spectra and the transmittance of GdAZO thin film demonstrate the application potential in transparent display. The transmission electron microscope image discovers the amorphous microstructure of the GdAZO thin film. The GdAZO TFTs manifests preferable transfer characteristics and output characteristics. The on-to-off current ratio is larger than 10

and the saturation mobility is about 10 cm

. The results imply that the GdAZO is a category of feasible candidate for oxide TFTs

besides

the GdAZO TFTs can serve as the drive devices in pixel circuits.
