In order to make all-printed thin-film transistors, the key issue such as the interfacing effect between printed electrodes and printed semiconductive channel layer has to be solved.In this study, thin film transistors were fabricated by inkjet printing of both semiconductive oxide channel and silver source-drain electrodes.A bottom-gate/top-contact configuration was utilized to avoid degradation of silver electrode conductivity. The morphology of printed semiconductive oxide channel depends on the volatility of solvent and has a great influence on the performance of the thin film transistor. Other factors influencing the performance include the composition ratio of oxide ink and layer thickness. Detailed studies are presented in the paper.
