我们创造了环境友好的低压离子调制晶体管（IMT），可以在纸基板上成功制造。一系列基于氯化胆碱（ChoCl）的离子液体（IL）被用作IMT中的电解质层。将不同的有机化合物与ChoCl混合以产生在室温下为液体或半液体的可溶液加工的深共熔混合物。在IMT的最终固体版本中，IL也通过使用商业粘合剂固化以产生可印刷的晶体管结构。IMT中的半导体层也被原始半导体和可生物降解的聚合物绝缘体的混合物取代。这减少了使用的昂贵和潜在有害的半导体的量，并且还提供了增加的晶体管性能，特别是增加了器件开关速度。然后，这些环保的IMT被用来在纸上创建环形振荡器、逻辑门和存储器。
We created environmentally friendly low-voltage, ion-modulated transistors (IMTs) that can be fabricated successfully on a paper substrate. A range of ionic liquids (ILs) based on choline chloride (ChoCl) were used as the electrolytic layer in the IMTs. Different organic compounds were mixed with ChoCl to create solution-processable deep eutectic mixtures that are liquid or semiliquid at room temperature. In the final, solid version of the IMT, the ILs are also solidified by using a commercial binder to create printable transistor structures The semiconductor layer in the IMT is also substituted with a blend of the original semiconductor and a biodegradable polymer insulator. This reduces the amount of expensive and potentially harmful semiconductor used, and it also provides increased transistor performance, especially increasing the device switching speed. These environmentally friendly IMTs are then used to create ring oscillators, logic gates, and memories on paper.
