    • -2 range. At lower SF densities TEM statistics becomes unreliable because of the finite area that can be sampled by this technique. At higher SF densities EPD statistics becomes unrealiable because individual etch pits merge and tend to cover the entire area samples by NOM.

    • The surface reconstruction observed during MEE on the Zn-predosed surface, during fabrication of the Se-rich CIL, or during ZnSe growth with BPR=0.4, was in all cases the 2 × 1 reconstruction, believed to correspond to a fully dimerized Se monolayer on the surface. See W. Chen, A. Kahn, P. Soukiassian, P. S. Mangat, J. Gaines, C. Ponzoni, and D. Olego, Phys. Rev. B 49, 10790 (1994). The normalized R values in Fig. 4 therefore, do not require corrections to take into account the effect of different ZnSe reconstructions, as in Ref. 47.

    • M. Funato, S. Aoki, S. Fujita, and S. Fujita, J. Appl. Phys. 82, 2984 (1997) proposed a sputter-etch method to obtain information on the Ga/As ratio near ZnSe/GaAs interfaces from XPS data. Their method was based on the assumption that Ga/As results for thick ZnSe overlayers should be more sensitive to the interface region than results for thin ZnSe overlayers. We have shown in Ref. 47 that the above assumption is incorrect and that no enhancement in the XPS sensitivity to the Ga/As interface ratio is expected upon a decrease of the II-VI epilayer thickness.

    • It should be noted that the theoretical 1.4 Å resolution of the TEM is fully demonstrated in some of the more elongated spots, but cannot be detected in every region of the image due to environmental instabilities.

    • note
    • Since the formation of a predominantly incoherent image require electron to scatter with phonons, in principle changes in HAADF contrast may also reflect changes in the local phonon density of states and/or in the phonon scattering cross section at the interface.

    • note
    • It should be noted that only a qualitative comparison is possible with this level of simulations. In particular, the dynamic range and grey scale in Fig. 6 have been chosen to emphasize the interface layer contrast, whereas in the experimental raw images of Fig. 5 the grey scale is comparatively more extended, so that the interface contrast appears somewhat lower than in the simulated images.
