    • Nonresonant tunneling times can be roughly estimated by the WKB theory (see also Ref.). Assuming that the s and levels in the CB of the InAs QD are about 130 and 100 meV below the GaAs CB edge, tunneling times of 5 ns and 100 ps are found, respectively.

    • In addition, the tunnel rate for the -electron at the X- -triplet state into the barrier will be reduced, which may increase the probability for a transition from the triplet X- to the singlet X- via an electron spin fli This leads to an enhancement of the + -component of the X- -signal at the cost of the + -line of the X0 -signal and thus to a reduction of the polarization degree for both lines.
