Extremely Low-Cost, Scalable Oxide Semiconductors Employing Poly(acrylic acid)-Decorated Carbon Nanotubes for Thin-Film Transistor Applications |
| 초록 |
In this study, we report, for the first time report, a simple bar-coating process of soluble metal oxide semiconductors, consuming the 0.1g of precursor solution in 4-inch sized devices with a cost of only 0.05 $. In order for resolving the issue of critical degradation in device performance observable in slow-evaporation based film formation processes, we incorporate the unprecedentedly-developed, poly(acrylic acid)-decorated multi-walled carbon nanotubes (MWNTs) in oxide semiconductors. It is demonstrated that a field-effect mobility is improved to the value of 7.34 cm2/Vs (improvement by a factor of 2) without any critical variation in threshold voltage and on/off current ratio. |
