Calculation considering excitonic effects, in comparison with the experimental results. (a) Plot of the probability density for the electron under the flat band and bending band. (b) Double logarithmic plot of the exciton energy shift versus sheet charge density for a 6-nm GaAsSb QW. (c) The same data as in the inset of Figure 1, fitted with another power law.
