Flexible low-power source-gated transistors with solution-processed metal–oxide semiconductors†
Source-gated transistors (SGTs) with Schottky barriers have emerged as extraordinary candidates for constructing low-power electronics by virtue of device simplicity, high gain, and low operation voltages. In this work, we demonstrate flexible low-power SGTs with solution processed In2O3 channels and Al2O3 gate dielectrics on ultrathin polymer substrates, exhibiting light area density (0.56 mg cm−2), low subthreshold swing (102 mV dec−1), low operation voltage (<2 V), fast saturation behaviors (0.2 V), and low power consumption (46.3 μW cm−2). These achievements pave the way for employing the unconventional SGTs in wearable applications where low-power dissipation and high mechanical flexibility are essential.
