Abstract
Results bn the study of the surface of Hg0.85Zn0.15Te show a low segre gation of its components and a weakly perturbed lattice after simple c hemical etching processes. The pseudo-dielectric function of this bulk semiconductor and of its anodic oxide is shown. The density of the in terface states in the gap is given for several compositions. The stoic hiometry of the oxidized surface was studied by angle resolved X-ray p hotoelectron spectroscopy. All results are consistent with a higher bo nd stability in mercury zinc telluride than mercury cadmium telluride.
