Abstract
Highlights •Cu2O/BiFeO3(BFO)/TiO2 photodetectors (PDs) form a stepped energy band structure at the heterojunction interface, and the interfacial electric field promotes the separation and transport of photogenerated carriers, improving the self-powered photodetection performance.•PDs based on ferroelectric materials can obtain different ferroelectric polarization states utilizing pre-biased voltage regulation to achieve programmable logic functions.
