The adsorption of argon ions with energies of 600-4000 eV on Ti films was investigated. The apparatus consists of a stainless steel vacuum chamber of volume about I5 litres evacuated by oil diffusion and getter-ion pumps. It is shown that the Ti films produced by vacuum evaporation adsorb only ionized argon. G F Ivanovskii and T D Radzhabov, Z/I Tekh Fiz, 35 (7)) 1965, 13/21318. 30 427.

The effect of the preparatory treatment of substrates on the perfection of epitaxial germanium films subsequently grown on these was examined. Preliminary treatment of the substrates in hydrogen at 850°C had a beneficial effect on growth, the best period of treatment being 40 min. By etching the substrates in a mixture of hydrogen chloride and hydrogen under polishing conditions, mirrorsmooth films devoid of all stacking faults were obtained.
