- Abstract
- We have fabricated the transparent TFTs using new oxide material (AZTO: Al-doped zinc tin oxide) as an active layer. The AZTO TFT showed good performance without post-annealing. The electrical characteristics were improved by the post-annealing up to 300 °C. The AZTO TFTs exhibited a mobility of 8~12 cm2/Vs, a subthreshold swing of 0.2~0.6 V/dec, and an on/off ratio of more than 109.
