碩士 === 國立交通大學 === 照明與能源光電研究所 === 106 === In this study, germanium nanowires were synthesized by Vapor-Liquid-Solid mechanism and up to 70% of printed nanowires are aligned within ±20° of primary sliding direction by using shear-force assisted contact printing. Three different densities of nanowire networks were incorporated with TIPS-Pentacene as nanocomposite-based organic thin-film transistors (Ge/TIPS-PEN OTFTs). Our results show that the mobility of Ge/TIPS-PEN OTFT with high density nanowires was increased about 10 times compared to that of pure TIPS-PEN device (0.024 to 0.248 cm2/Vs). Additionally, we found that the electrical characteristics of Ge/TIPS-PEN OTFTs without oxide shell etching were similar to those of pristine TIPS-PEN OTFTs. For air stability test, however, the mobility degradation rate of nanocomposite Ge/TIPS-PEN transistors is more distinctive than that of pristine TIPS-PEN OTFTs.
