Abstract :InTiZnO thin-film transistors (ITZO TFTs) with Al2 O3 gate dielectrics are fabricated by magnetron sputtering at room temperature. The bottom-gate-type ITZO TFTs with amorphous Al2 O3 gate dielectrics are operated in the enhancement mode and exhibit a mobility of 50.4 cm2 /V?s, threshold voltage of 1.2 V, subthreshold swing of 94.5 mV/decade, and on/off-current ratio of 7× 106 . We believe that ITZO deposited at room temperature is an appropriate semiconductor material to produce high-mobility TFTs for developing flexible electronic devices.
