    • 0(z) = cδ(z) and c<0, along with methods for rectifying these problems. Since these corrections amount to modifying the spatial dimension d in the effective "diffusion coefficient" (l/2d) to be a function of c, these modifications may readily be combined with the results presented here for surface segregation.

    • λ,λ are now dependent on both composition and density and are, therefore, varying through the density profile. A simplified representation ensues by using Eq. (35) only as the bulk interaction parameters and ignoring their near surface variation. Similarly, the use of more realistic models for the translational entropy [see, for instance, Ref. 14 and R.

    • H.-P. Deutsch and R. Dickman, ibid. 93, 8983 (1990)] leads to nonlinear integral equations for the density profiles and, hence, to the loss of analytical tractability.
