A ternary inverter is demonstrated based on an organic antiambipolar transistor (AAT), in which the output logic states can be precisely controlled with appropriate optical signals. First, the photoresponse of AATs consisting of PTCDI‐C8 and α‐6T layers is systematically investigated. Under visible light, the Λ‐shaped transfer curve of the AATs undergoes a noticeable broadening due to the optically induced threshold voltage shift in both the PTCDI‐C8 and α‐6T controlled ranges. Under ultraviolet light, broadening is observed only on the α‐6T side. These contrasting impacts of the two light signals enable to tune the balance of the ternary logic states in the inverters, including the output voltage levels and the ratio of the respective logic states. Such optically controlled ternary logic circuits possess great potential for their application in next‐generation optoelectronic devices.

基于有机反双极晶体管的光控三元逻辑电路

演示了基于有机反双极晶体管（AAT）的三元逆变器，其中可以使用适当的光信号精确控制输出逻辑状态。首先，系统地研究了由PTCDI-C8和α-6T层组成的AAT的光响应。在可见光下，由于在PTCDI-C8和α-6T控制范围内的光感应阈值电压偏移，AAT的Λ形传递曲线经历了明显的加宽。在紫外线下，仅在α-6T侧观察到增宽。两个光信号的这些相反的影响使得能够调节反相器中三元逻辑状态的平衡，包括输出电压电平和各个逻辑状态的比率。
