An extension of the memristive system: From tunable conductance to reconfigurable photoresponse

https://phys.org/news/2023-02-extension-memristive-tunable-reconfigurable-photoresponse.html

"non-volatile photo-memristor... reconfigurable responsivity modulated by charge and/or photon flux through it and stored in device... computationally complete logic with photoresponse-stateful operations... same photo-memristor is both logic gate and memory... photoresponse as physical state variable instead of light, voltage and memresistance... two-terminal device based on ion migration, not limited by thickness... can increase film thickness to absorb more photons and large short-circuit photocurrent"
