| Outline of Final Research Achievements |
In this research, we have developed new silver nanoparticle ink, which can control the work function after electrode fabrication, for high performance organic semiconductor device. By intentionally introducing a large polar organic molecule on the silver nanoparticle surface as the organic protective molecule, the work function of the printed silver nanoparticle electrode can be controlled by the electrode sintering. The controlled work function can reduce energy barriers with organic semiconductors and printed electrode, lead to higher device performance such as low voltage operation of organic transistors and reduced parasitic resistance in integrated circuits.
