Evaluation scheme of the random telegraph signal (RTS). (a) Single photon stream from the resonant excitation of the exciton transition, recorded for about 5 min (b,c) Binned photon counts per \(t_{\textrm{bin}}\) (left panel) and corresponding histogram (right panel) for two binning times \(t_{\textrm{bin}}\) (b \(t_{\textrm{bin}}=20\,\upmu \hbox {s}\); c \(t_{\textrm{bin}}=2\,\upmu \hbox {s}\)). The charge state of the dot is determined by applying a threshold photon number (dashed red line). (d) The waiting-time distribution is evaluated by the length and frequency of the time periods of the on (\(\tau _{\textrm{on}}\)) and off state (\(\tau _{\textrm{off}}\)), respectively. (e) The full-counting statistics of the data in Fig. 2b, i.e. the probability to find N tunnel events in a given time period \(\Delta t=20\) ms.
