Memristive Behavior in Carrier Accumulation-Based Optical Modulators.

ABSTRACT: Memristive switching and field-effect modulation form the basis of many optoelectronic devices, yet despite their complementary properties, they are typically realized in separate architectures. Here, we demonstrate an optoelectronic platform that combines carrier accumulation/depletion (CAL/CDL) and electrochemical metallization (ECM) effects within a single device. By engineering a Ag/ITO/SiO₂/Ag stack and tuning the ITO carrier concentration, we achieve electrically driven transitions between volatile and nonvolatile optical states. Spectroscopic ellipsometry and electrical measurements, enhanced by well-defined optical resonances and a large active area, reveal that low-voltage modulation originates from field-induced carrier redistribution at the ITO/SiO₂ interfa
