    • For example, to obtain a balanced system in a structure with three 140-Å-wide wells and barriers similar to those of Fig. 1, Nsapprox 2 times 1010 cm-2 is needed. Alternatively, to have a balanced system with Ns= 2 times 1011 cm-2, each of the three (equally wide) wells has to be approx 70 Å wide.

    • In a many-body picture, is also possible that the subband separations may change as a function of B. For example, in a double-layer structure, the reduction and collapse of subband gap E2- E1 at high B has been reported (see Refs. 2 and 3 ).

    • It is worth noting that the ν = case 5 over 7 state predicted in Ref. 1 has a lower density in the central layer than the two side layers.
