- 초록
- We demonstrate stretchable organic thin-film transistors (OTFTs) on a polyimide stiff-island/elastomer substrate. All processes are performed entirely at elastomer-compatible temperatures. We confirm the basic properties of the poly(vinylidene fluoridetrifluoroethylene) [P(VDF-TrFE)] with a poly(methyl methacrylate) (PMMA) blended film on the elastomer substrate and evaluate the characteristics of the fabricated stretchable OTFTs. A field-effect mobility of 3.4 × 10-3 cm2 V-1 s-1, an Ion/Ioff ratio greater than 103, a subthreshold voltage swing of 12.5 V/decade, and a gate leakage current of 10-10 A were obtained. The endurable maximum strain was approximately 50% for the OTFTs without degrading the field-effect mobility formed on the elastomers.
