(a) The logarithmic plot and linear fitting of light-emitting memory (LEM) at high resistance state (HRS) before 8 V bias. (b) The current intensity of LEM, divided by V2, as a function of V−1 at HRS after 8 V bias. (c) The current intensity of LEM, divided by V2, as a function of V−1 at low resistance state (LRS).
