Forward curves on semilog scale (a) and on linear scale (b). The points represent experimental data while the curves represent the simulations. From bottom to top, the temperatures of the curves increase from 300 to 470 K in steps of 10 K.
Solid points represent the relation between saturation current and temperature obtained from Fig. 1 and the line represents the least-square fit. Solid points in the inset represent the series resistances at various temperatures. The scattering of the series resistances around the least-square fit (solid line) is caused by the different probing pressures.
