We report on high-performance ink-jet-printed amorphous zinctinoxide (α-ZTO) thin-film transistors (TFTs) and simple inverter circuits. The solution-processed α-ZTO layer was directly printed on source/drain electrodes and then thermally treated by using rapid thermal annealing process. The ink-jet-printed α-ZTO TFTs (W/L =100μm/10\μm) have shown a carrier mobility of 4.98 cm2Vs with an on/off current ratio that is greater than 109 and a subthreshold slope of 0.92 V/dec. The α-ZTO TFT-based inverter operation was good with acceptable logic level conservation.
