제목 Unraveling the Issue of Ag Migration in Printable Source/Drain Electrodes Compatible to Versatile Solution-Processed Oxide Semiconductors for Printed Thin-Film Transistor Applications
초록 For a recent decade, the solution-processable, printable oxide thin-film transistors have gained the tremendous attention toward low-cost, large-area electronics. The various oxide semiconductors have been suggested with moderate field-effect mobilities along with excellent optical properties and environmentally-stable characteristics. However, for the case of printable metallic source/drain electrodes, they have suffered from the undesirable electrical/thermal migration at an interfacial stack of oxide semiconductors and metal electrodes. In this study, we have designed the oleic acid-capped Ag nanoparticles, readily applicable to printable, viscous fluids, in order for suppressing effectively the significant migration of Ag phase as well as for facilitating high field-effect mobilities comparable to the values of counterparts with evaporated Al source/drain electrodes. An origin for the role of surface-capped Ag nanoparticles is clarified with a comparative studies using commercial and thermoplastic triblock copolymer-incorporated Ag flake-pastes, based on a combinatorial investigation by X-ray photoelectron spectroscopy and X-ray absorption spectroscopy.
