A multi‐valued logic (MVL) technology is considered to be a promising way to improve data processing capabilities with higher bit density. Unique negative transconductance characteristics in van der Waals (vdW) p‐n heterojunction‐based devices enabled recent demonstrations of MVL circuits. Herein, inkjet‐printed ternary inverters are presented for the first time by connecting anti‐ambipolar transistors, based on indium oxide/single‐walled carbon nanotube (SWCNT) heterojunctions, and SWCNT transistors. Inkjet printing allows systematic control of anti‐ambipolar transistor characteristics by forming vdW heterojunctions reliably. The anti‐ambipolar transistor characteristics are widely tuned by simply changing the number of SWCNT printing in heterojunction channels. Tunable middle logic voltages in ternary inverters are achieved by using the changes in anti‐ambipolar transistor characteristics. This work provides a guideline for tuning device characteristics of anti‐ambipolar transistors and ternary inverters.

具有可调中间逻辑电压的喷墨印刷三元逆变器电路

多值逻辑（MVL）技术被认为是一种以更高的比特密度提高数据处理能力的有前途的方法。范德华（vdW）p-n异质结器件中独特的负跨导特性使MVL电路的最新演示成为可能。本文中，首次通过连接基于氧化铟/单壁碳纳米管（SWCNT）异质结的反双极晶体管和SWCNT晶体管，展示了喷墨印刷的三元逆变器。通过可靠地形成vdW异质结，喷墨打印可以系统地控制反双极晶体管的特性。只需更改异质结通道中的SWCNT印刷数量，即可广泛调节反双极晶体管的特性。通过使用反双极晶体管特性的变化，可实现三元逆变器中可调的中间逻辑电压。这项工作为调整反双极型晶体管和三元反相器的器件特性提供了指南。
