The composition, densities of state of electrons in the valence band, and parameters of energybands of ultrathin CdMgTe layers created on the surface of single-crystal CdTe(111) will bestudied by implantation with Mg+ ions with energies E0=1 keV with different doses D≈2×1015–6×1016 cm−2 using the methods of Auger electron spectroscopy, photoelectron spectroscopy,and energy dependences of secondary electron emission coefficients in this article. It is shownthat after ion implantation, the value of Eg decreases sharply, which is explained by the disorderingof the near-surface layer, the formation of various defect levels with a high density inthe forbidden zone, and the surface enrichment with Mg and Cd atoms. After annealing, aCd0.6Mg0.4Te film with a thickness of d~40 Å was formed. The band-energy parameters andthe density of states of the valence band electrons of this film were determined.
