Abstract
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 cm 2 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 cm 2 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.
