Figure 1

The output characteristics (IDS vs. VDS) of ZTO TFTs for the sample (a) 33ZTO and (b) 50ZTO measured at different VGS. In (c) and (d), the transfer characteristics (IDS vs. VGS) of ZTO thinfilm transistors for the sample 33ZTO and 50ZTO, respectively. In both the TFTs, active semiconductor channel W/L ratio was fixed to 38.
