a constant significantly reduces the computational complexity of 3D-ME modeling. Giving a full numerical evaluation of , for all possible situations, is in practice unfeasible, because and r$_{v}$ depend on the electron as well as the hole concentrations. For simplicity, we only show here the results of numerical evaluations for the case of c = c$^{e}$. I the next section, we show by direct comparisons of results from ME and KMC simulations that the conclusions from this section are also well-applicable when the electron and hole concentrations are different. In Figs. 12 parts (a)-(d), , and r$_{v}$ /EGDM, nd MMA , respectively, are given as a function of = j k$_{B}$T . For evaluating we run KMC simulations for periodic boundary boxes. A relatively low electric held, F = 10 7 V/m, is applied. For unipolar cases, the mobility ni is calculated by hlling the box with the desired concentration of a single type of charge carrier. For bipolar cases, the mobility ¾ is calculated by hlling the box at random sites by the desired concentration of both types of charge carriers. The 3D Coulomb interaction between all charge carriers is explicitly considered. Subsequently, we evaluate The function r c, ), dehned in Eq. (S7), is evaluated using 3D-ME simulations for a box with periodic boundary conditions, randomly filled with non-interacting electrons and holes (each according t o a Fermi-Dirac distribution corresponding t o the carrier concentration of interest). The functions / E$_{G}$ DM and /MMA are calculated from Eqs (S9) and (S18), respectively. The overall effect of these factors on the parameter t i shown in Fig. 12 part (e). It is seen that for 3 < < 5 and c < ICC$^{3}$, t depends only weakly on and c. We have extensively studied whether it would be admitted t o use a single value of the A parameter for a large number of devices and experimental conditions of practical relevance, and we have found that that is t o a good approximation indeed possible when using A C (0.024 – 0.005), when combined with B = —0.154. Therefore, in the main text, we use the following simplified form of the 7 formula in the 3D-ME simulations:
