Abstract

We report on the realization of dual-channel organic field-effect transistors (FETs). These devices have a four-terminal configuration with a polymeric semiconductor p -channel, a small molecule semiconductor n -channel, and a polymeric gate dielectric. The polymeric p -channel and the small molecule n -channel are coupled across the gate dielectric. Both the p -FET and the n -FET exhibit acceptable device characteristics at ∫ VDS ∫ ≤50 V and ∫ VG ∫ ≤50 V, in which the performances of the p -FET and the n -FET are comparable. The p -FET and n -FET respond to isopropyl alcohol and ethanol vapors with significant sensitivities.
