Effect of Polarity of Ionic Molecules on Characteristics of Solid-State Electrolyte-Gated Organic Transistors |
| 초록 |
The soft dielectric materials for flexible and solution-processed organic field-effect transistors (OFETs) have been actively investigated since the performance and operating voltage of OFETs strongly depend on not only material itself but also the quality of gate dielectric layer. Solid-state-electrolyte gate insulators(SEGIs) is one of candidates due to giant field effect mobility and ultra low operating voltage can be achieved by a high capacitance of the SEGI. In particular, unlike other ion gel as a dielectric layer, the metal film as a gate electrode can be deposited on SEGI layer due to its solid nature of composition of high-k dielectric material [P(VDF-TrFE)] and the ion gel blends including P(VDF-HFP) with ionic liquids. In this paper, we investigate the effect of polarity and size of ion molecules in SEGI formulation on property of top-gate bottom-contact FETs. Details of the effect of ionic molecules in organic SEGI transistors are discussed in our presentation. |
