The resistive switching (RS) mechanism of hybrid organic-inorganic perovskites is an open question until now. Here, a switchable diode-like RS behavior in MAPbBr₃ single crystals using Au (or Pt) symmetry electrodes is reported. Both the high resistance state (HRS) and low resistance state (LRS) are electrode-area dependent and light responsive. We propose an electric-field-driven inner p-n junction accompanied by an interface trap-controlled SCLC mechanism to explain this switchable diode-like RS behavior in MAPbBr₃ single crystals.
