    • This estimation is based on the assumption that only QD ground states are available, that all injected electrons recombine radiatively in the QDs, and that the current is distributed homogeneously throughout the sample. The calculated value for the QD ground state occupation should, however, be a reasonable estimate, since the corrections due to these factors partly cancel each other.

    • This effect should at least play a role in weakly confined InGaAs QDs at close to zero magnetic fields, cf. E. Tsitsishvili, R. v. Baltz, and H. Kalt, Phys. Rev. B 0163-1829 72, 155333 (2005). A closer theoretical study would be required for conforming the validity at higher magnetic fields and for QDs with a strong confinement. 10.1103/PhysRevB.72.155333 (Pubitemid 43022228)
