Dynamics of charge generation. (a) Time evolution of the charging fidelity, calculated using the Master equation for an InP nanowire with an array of crystal-phase QDs of dimensions \(\left[{d}_{1},{d}_{2},{d}_{3},{d}_{4},{d}_{5}\right]=\left[11\;\mathrm{nm},14\;\mathrm{nm},9\;\mathrm{nm},15\;\mathrm{nm},8\;\mathrm{nm}\right]\). The dashed lines indicate the threshold set to define the pumping time. (b) Maximum fidelity (red) and charging time (blue) as a function of total structure length, \(L={d}_{1}+{d}_{2}+{d}_{3}+{d}_{4}+{d}_{5}\). The circles and dashed lines mark the values for \(L=57\;\mathrm{nm}\), corresponding to the structure used in (a). The laser Rabi frequencies in both plots are \({\Omega }_{A}={\Omega }_{B}=20\gamma\), ensuring the condition \(\Omega \gg \gamma\).
