Lead-Free FA3BiI6 Perovskite Memristor for Logic Gate Circuits and Data Encryption
The heavy metal toxicity of lead-based halide perovskites hinders their practical application in memristors. Herein, we report a lead-free FA3BiI6-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,...
