Abstract
Figure 5 from the article on “Chemical Interfaces: Structure, Properties, and Relaxation” by A. Ourmazd should have been printed in color on p. 61 of the September 1990 issue of the MRS BULLETIN. The color figure to the left can be cut from the current issue and pasted over the appropriate area on p. 61 of the September 1990 issue. This figure is a three-dimensional representation of the analyzed lattice image of Al0.37Ga0.63As grown on GaAs after a 2-min interruption. The unit cells are 2.8 A squares. The height of a unit cell represents its composition, and the color changes represent statistically significant changes in composition over and above random alloy statistics.
