Tuning Ambipolarity of the Conjugated Polymer Channel Layers of Floating‐Gate Free Transistors: From Volatile Memories to Artificial Synapses (Adv. Sci. 31/2022)

Floating‐Gate Free Transistors In article number 2203025, Yu‐Ting Yang, Wen‐Ya Lee, Chu‐Chen Chueh, and co‐workers reveal a floating‐gate‐free transistor based on the ambipolar diketopyrrolopyrrole‐based conjugated polymers. The correlations between the channel's ambipolarity, memory characteristics, and synaptic behaviors are systematically investigated. The μh/μe mobility ratio is critical for controlling device characteristics from nonvolatile memory to artificial synapses. [Image: see text]
