Experimental and First‐Principles Study of Visible Light Responsive Memristor Based on CuAlAgCr/TiO₂/W Structure for Artificial Synapses with Visual Perception (Adv. Electron. Mater. 5/2023)

Abstract

Artificial Synapses An important building block for a visual bionic system is efficient artificial synapses. Analog to a biological synapse, the CuAlAgCr/TiO2/W optoelectronic memristor under light stimulation can integrate sensing, storage and computing functions, showing great potential in optical synaptic function for the construction of artificial vision systems.

Achieving Reliable and Ultrafast Memristors via Artificial Filaments in Silk Fibroin

“…Therefore, we have measured highresolution I-V switching curves of the Ag/SF/Au memristor (Figure 2g) and obtained an SS of less than 0.01 mV dec −1 , which is the smallest SS to the best of our knowledge (benchmarked in Figure 2h). [43][44][45][46][47][48][49][50][51][52] The pulse-mode measurement further showed a sub-100 ns resistive switching speed (Figure 2i), corresponding to a low operation energy of ≈14 pJ. The switching speed of Agbased memristors is mainly limited by the Ag ions' transport velocity in the insulating layer, which was controlled by the applied electric field.…”
