摘要
High-performance, full-swing inverters implementedwith InGaZnO thin-film transistors (TFTs) have been demonstrated capable of operating at a very low-voltage. The threshold voltage of the load and drive TFTs were modified through careful change of the gate dielectric anodization voltage. Both the load and drive TFTs show excellent electrical properties, including a current ON/OFF ratio > 10(6) and a subthreshold swing close to the theoretical limit. As a result, the inverters show high voltage gains up to 34 at a supply voltage of only 1 V as well as high noise margins> 92% of the theoreticalmaximum. The devices and the fabrication processmight have potential applications in future wearable and disposable electronics where low cost and low power are vital.
