    • In Eq. 1, we have considered that the mixing of heavy-hole and light-hole subbands is weak. For the low-lying states of the structures, we study that this can be shown to be true.

    • For the NR, the CI basis is built from the 28 (12) lowest single-hole (electron) spin orbitals with mi =0 (i=e,h), the eight (four) lowest with mi =±1, and the four lowest with mh =±2. For the NC, we use the eight (six) lowest spin orbitals with mi =0, the six (four) lowest with me =±1, the four (two) lowest with me =±2, and the two lowest with mh =±3.

    • Electron-hole exchange and self-energy interactions are neglected as they do not influence the trends we report here. In particular, self-energy corrections consist roughly in a shift of the corresponding single-particle energy spectra, yielding minor effects on the Coulomb interactions. This is due to the nearly flat profile of the self-polarization potential in the medium with larger dielectric constant [see, e.g., 10.1063/1.445676

    • It is worth noting that our estimated enhancement of Veh for the NR (265 meV at εout =1.75) is in the range of experimental measurements (∼240-300meV) (Ref.).
