Printing technology has received considerable attention in various academic and industrial eco-friendly applications with respect to processability. In particular, the printed electronics is of interest in a variety of fields such as transistors, radio-frequency identification tags, flexible displays, electronic solar cell, and batteries. In this work, we successfully demonstrated the Ag nanoparticle (NP) source/drain (S/D) electrodes using screen printing process. We carried out a systematic study of the screen printing of Ag NP ink to derive the optimum condition of conductivity and stability that can control the Ag NP S/D electrodes. In addition, we investigated the effect of surface modification on the crystal morphology of a DNTT semiconductor layer grown on the surface, as well as the device performance under gate-bias stress of the corresponding organic thin film transistors (OTFTs). |
