High Scale-Cost-Performance Manufacturing of Organic Single-Crystal Electronics

Abstract

Large-area electronics have a natural eagerness to manufacture electronic devices with high scale-cost-performance metrics for emerging applications, spanning from the Internet of Things to flexible and wearable electronics. Printing technologies facilitate high-throughput production of reliable, stable, and cost-effective devices, but the suboptimal electronic quality of solution-printed semiconducting materials has constrained device performance across broader application spaces. Here, fully printed, monolithically integrated, large-scale thin-film transistor (TFT) arrays featuring high-quality organic single-crystalline films as device channels are reported. This breakthrough is achieved through sophisticated fluid dynamic engineering across multiple and uneven heterointerfaces. These fully-printed TFTs unlock previously inaccessible theoretic performance boundaries, delivering exceptional electrical performance with a near-ideal subthreshold swing of 59.4 mV dec−1, a record-high mobility of 13.8 cm2 V−1 s−1, and low operation voltages. This approach through large-scale production is further validated, successfully fabricating 2500 organic thin-film transistors (OTFTs) over 30 cm2 area with a remarkable device yield exceeding 99.92%. Furthermore, the versatility of this fully printed organic TFT array as an active matrix integrated multisensory platform is showcased, signifying a significant advancement in printed electronics.
