Results from the work of Bennett et al. describing the influence of a vertical electric field on the emission of InAs/GaAs QDs.(a) FSS of several QDs vs. the relative electric field F − F0, where F0is the field where the FSS of each QD reaches its minimum, s0. (b) Orientation of the linear polarization of the emitted light with respect to the crystal axes vs. the relative electric field for the same QDs as presented in (a).
