11. R is the spontaneous emission rate between the lowest and highest states of the second and first minibands, respectively, calculated from Fermi's golden rule.
12. The low energy shoulder in the spectrum at 3 mA of sample D2135 (Fig. 4) is attributed to diagonal transitions between the ground state of the injector and the first miniband.

14. ΓL≅0.4 eV). This will greatly reduce the radiative efficiency for photon energies >0.4 eV due to intervalley (Γ-L) scattering (γ=0.1 ps). The identification of the small oscillations in the spectrum as transitions between the calculated states of the finite superlattice is made difficult by their strong broadening (∼10 meV).
