Light‐Induced Synaptic Effects Controlled by Incorporation of Charge‐Trapping Layer into Hybrid Perovskite Memristor

Abstract Organic‐inorganic perovskites despite being known for their extraordinary performance in solar cell research areas are also a workhorse in the field of unconventional information processing. Here, a neuromimetic behaviour is presented in a perovskite device with the potential to act as an artificial synapse. In addition, perovskite layer is combined with one of the non‐stoichiometric polymeric forms of carbon nitride (C 3 N 4 ). Such a device can operate not only according to the principles of non‐von Neumann architecture but also utilizes two different stimuli as information carriers–electric current and/or light. This in turn can lead towards the development of next‐generation information processing/storage units.
