Scattering processes in the WL-DQD system. Each process has two lines of the same color for two carrier processes (ee and eh or he and hh with e: electron and h: hole). Only the exchange process (black line), contributed to by other processes, appears lonely. Cap: capture, relax: relaxation, mix: mixed, and exch: exchange processes. The processes are numbered according to their appearance in Table 1. For example, p1 refers to the process no. 1 in Table 1
