An inevitable wide bandgap nature of metal-oxide semiconductors generally prohibits their application in visible light-driven optoelectronic devices. Herein, a simple stack of TiO2 on IGZO was proposed to promote a wide spectral range absorption of light. Based on this, various applications such as memory and synaptic characteristics are demonstrated.
