Lead-Free FA<sub>3</sub>BiI<sub>6</sub> Perovskite Memristor for Logic Gate Circuits and Data Encryption
Listed in ZivaHub
The heavy metal toxicity of lead-based halide perovskites hinders their practical application in memristors.
Description
Herein, we report a lead-free FA<sub>3</sub>BiI<sub>6</sub>-based sandwich-structured memristor. The device exhibits stable bipolar resistive switching with negligible degradation over 200 DC cycles and a retention time of 3000 s, and excellent uniformity in switching voltages and resistance states.
Mechanistic analysis reveals that electric-field-driven Ag<sup>+</sup> migration, inducing local conductive filaments, is the key to the resistive-switching behavior. Pulse tests demonstrate that the device can mimic various biological synaptic plasticity, including excitatory postsynaptic current (EPSC), paired-pulse facilitation (PPF), and long-term potentiation/depression (LTP/LTD). Furthermore, OR, AND, and XOR basic logic gate circuits are constructed, with XOR operations being employed for lossless symmetric encryption/decryption of RGB color images, and the original image features being completely masked.
