Sub-thermionic, ultra-high-gain organic transistors and circuits

Abstract The development of organic thin-film transistors (OTFTs) with low power consumption and high gain will advance many flexible electronics. Here, by combining solution-processed monolayer crystal, ferroelectric HfZrO x gating van der Waals fabrication, we realize OTFTs that simultaneously deliver transconductance sub-60 mV/dec switching, under one-volt operating voltage. overall optimization transconductance, subthreshold swing output resistance leads to transistor intrinsic amplifier voltage over 5.3 × 10 4 1.1 , respectively, which outperform existing technologies using organics, oxides low-dimensional nanomaterials. We further demonstrate battery-powered, integrated wearable electrocardiogram (ECG) pulse sensors can amplify human physiological signal 900 times fidelity. are capable detecting weak ECG waves (undetectable even clinical equipment) diagnosing arrhythmia atrial fibrillation. Our sub-thermionic OTFT is promising for battery/wireless powered yet performance demanding applications such as electronic skins radio-frequency identification tags, among others.
