Figure 6. Simulation results of the RESET switching with variable E_a and R_⊥.

(a) 10% G–V curves randomly selected from 1250 RESET cycles. (b) and (c) scatter plots for RESET1 (red circles) and RESET2 (blue circles). (d) Evolution of the conductance distribution with V in 1250 RESET cycles. In this simulation, E_a is assumed to obey a constant distribution between 0.8 eV and 1.4 eV, and R_⊥ is assumed to range between 2 × 10⁶ K W⁻¹ and 1 × 10⁷ K W⁻¹ and obey a Gaussian distribution with a mean of 4 × 10⁶ K W⁻¹ and a standard deviation of 3 × 10⁶ K W⁻¹.
