Abstract Emulating key synaptic functions in electronic devices is quite significant bioinspired applications. Artificial thin film transistors (TFT) offer a promising solution for efficient synapse simulation. Herein, artificial synapses based on indium–gallium–zinc oxide (IGZO) TFT are fabricated and the photoelectric plasticity investigated.
