Figure 5: (a), (b), (c): Interferogram contrast 𝐶 ( 𝑡 ) of the photoluminescence signal of a single InGaAs QD at 10 K, on semilogarithmic plots, for three gate voltages: 0 . 2 4  V (a), 0 . 2 2 (b), and 0 . 2  V. Data (squares), theoretical fits corresponding to | 𝜙 1 ( 𝑡 ) 𝜙 𝐺 𝑁 ( 𝑡 ) | (solid line). (d): Tunneling time versus gate voltage. Data (symbols), theoretical fit (solid line). The horizontal line indicates the capture time 𝜏 = 5 0 0  ps.
