The TaOx/ZnON thin-film stack showed a more uniform distribution of nanocrystalline ZnON with an increased stoichiometric anion lattice compared to control ZnON thin-films. Significantly, improved mobility of 89.4 cm2/Vs were achieved for TaOx/ZnON TFTs. This improvement can be explained by the removal and passivation effect of TaOx film on ZnON.
