Simulated memcapacitance in symmetric and asymmetric membranes in decane. a Percentage contributions of EW and EC mechanisms to the steady-state change in capacitance versus excitation frequency. Percentages were computed from the outputs of simulating the geometrical and total capacitive responses of a DPhPC bilayer in decane (Fig. 6). b Simulated Q-v loops using the state equations and fitted parameters provided in Table 1. These traces capture the Q-v shape and frequency dependence observed in our experimental results (see Table 1 for MAPE and R2 values) (Fig. 2). c Simulation showing the ~20% cumulative decrease in membrane thickness (red) and ~35% increase in membrane radius in response to a rectangular voltage pulse train (150 mV, Ton = 2 ms, Toff = 1 ms). d Simulated peak currents (red and green, respectively) and capacitance (blue) responses corresponding to the symmetric DPhPC membrane in decane described in (b) and (c) and the asymmetric DPhPC:DOPhPC membrane in decane. The model captures both forms of short-term plasticity observed in Fig. 5
