11. b represents the unperturbed binding energy of the tree exciton and neglects any contribution of localization at sample inhomogeneities. Note that although localization is not accounted for either in the mass-action law or in the resulting distribution function, we account for localization effects in the calculation of the nonlinear absorption profiles by broadening the Gaussian exciton density of states and the quantum-well (step-function) density of states, using the usual inhomogeneous line-broadening parameter gamma.

16. Biexciton lasing has recently been claimed in ZnCdSe/ZnSe MQW's with extremely sharp luminescence lines. We do not have any evidence of biexciton recombination in the samples investigated in this research. See F. Kreller, M. Lowish, J. Puls, and K. Henneberger, Phys. Rev. Lett. (to be published).
