The materials combination of inkjet-printed single-walled carbon nanotubes (SWCNTs) and zinc tin oxide (ZTO) is very promising for large-area thin-film electronics. We compare the characteristics of conventional complementary inverters and ring oscillators measured in air (with SWCNT p-channel field effect transistors (FETs) and ZTO n-channel FETs) with those of ambipolar inverters and ring oscillators comprised of bilayer SWCNT/ZTO FETs. This is the first such comparison between the performance characteristics of ambipolar and conventional inverters and ring oscillators. The measured signal delay per stage of 140 ns for complementary ring oscillators is the fastest for any ring oscillator circuit with printed semiconductors to date.
喷墨打印的单壁碳纳米管 (SWCNTs) 和氧化锌锡 (ZTO) 的材料组合非常适合大面积薄膜电子学。我们比较了在空气中测量的传统互补反相器和环形振荡器的特性（使用 SWCNT p 通道场效应晶体管 (FET) 和 ZTO n 通道 FET）与由双层 SWCNT/ZTO FET 组成的双极性反相器和环形振荡器的特性。这是首次对双极性和传统反相器和环形振荡器的性能特性进行比较。测量的互补环形振荡器的每级信号延迟为 140 ns，是迄今为止使用印刷半导体的任何环形振荡器电路中最快的。
