| Outline of Final Research Achievements |
The present report describes a method for the room-temperature printing of electronics, which allows thin-film electronic devices to be printed at room temperature without the application of heat. The development of π-junction gold nanoparticles as the electrode material permits the room-temperature deposition of a conductive metal layer. Room-temperature patterning methods are also developed for the Au ink electrodes and an active organic semiconductor layer, which enables the fabrication of organic thin-film transistors through room-temperature printing. The transistor devices printed at room temperature exhibit average field-effect mobilities of 7.9 and 2.5 cm2 V-1 s-1 on plastic and paper substrates, respectively. These results suggest that this fabrication method is very promising as a core technology for low-cost and high-performance printed electronics.
