Figure 1. Ensemble-averaged evolution of electron probability density in the plane perpendicular to the donor (grey area) and acceptor (8 × 16 × 16 nm³ domain) interface at different times following photoexcitation for the indicated values of inter-acceptor coupling J_A.

The rightmost column shows the corresponding absolute charge separation distance d_abs(t) (black traces) and delocalization radius l(t) (blue traces). Filled blue circles illustrate the extent of electron coherence at a given time. The color scale at the bottom describes the probability of finding the electron at the indicated distance from the interface.
