Abstract
Semiconductor devices based upon silicon have powered the modern electronics revolution through advanced manufacturing processes. However, the requirement of high temperatures to create crystalline silicon devices has restricted its use in a number of new applications, such as printed and flexible electronics. Thus, developments with high mobility solution-processable metal oxides, surpassing α-Si in many instances, is opening a new era for flexible and wearable electronics. However, high operating voltages and relatively high deposition temperatures required for metal oxides remain impediments for the flexible devices. Here, the fabrication of low operating voltage, flexible thin film transistors (TFT) using a solution processed indium oxide In2 O3) channel material with room temperature deposited anodized high-κ aluminum oxide (Al2 O3) for gate dielectrics are reported. The flexible TFTs operates at low voltage Vds of 2 V, with threshold voltage Vth 0.42 V, on/off ratio 103 and subthreshold swing (SS) 420 mV/dec. The electron mobility (μ), extracted from the saturation regime, is 2.85 cm2/V.s and transconductance, gm, is 38 μS.
