Abstract

Photosensitivity to ultraviolet (UV) light for zinc oxide (ZnO) resistance random access memory (RRAM) with transparent electrode was investigated and characterized in this paper. The resistive switching properties were affected severely through oxygen manipulation by UV light irradiation. To clarify the switching mechanism, conduction current fitting was applied and meanwhile a reaction model was proposed to explain the origin of drastic current variation. UV light-assisted oxygen manipulation in ZnO RRAM is an efficient method to modify device switching behavior, and this investigation also unveils the interesting phenomenon of transparent electrode RRAM under UV light illumination condition.
