Abstract

From the beginning of this century, printed electronics (PE) has attracted large research as well as commercial interest. A large variety of functional devices belong to the PE umbrella, starting from conducting inks, sensors, energy storage and conversion devices, lighting, and of course logic and memory electronics. Here, it is important to note that for fully print electronic circuits, all the basic building blocks, such as, TFTs, memories, capacitors, and diodes must be fabricated by solution process/printing techniques with sufficient performance, reliability and lifetime. However, while printed TFTs have attracted the majority of attention, the other circuit components have largely been under-represented. In this regard, here we demonstrate ink-jet printed Ag/a-IGZO/ITO Schottky diodes with rectification ratio more than 10⁶ for low voltage and low frequency applications. In this study, we show that the diodes can be operated at as low as 1 V, till 3 kHz operation frequency and can carry substantially large current density of 45 A (cm) ^(-2). © 2022 IEEE.
