A thin layer on the surface of single‐crystal germanium produced by 60Co‐gamma irradiation has been found. This layer can only be produced on specimens which were irradiated in air. Several infrared absorption bands with peak absorptions at 3, 6, 6.85, 11.5, and 12.7 μ are associated with the layer. Of these bands, only the 11.5‐μ band has been identified as resulting from germanium dioxide which was formed on the surface by chemical reaction of germanium with oxygen and/or ozone. The origins… Expand

Effects of substrate bias and nitrogen flow ratio on the resistivity, composition, crystal structure, and reflectance of reactively sputtered hafnium-nitride film
Abstract Hf-N films were sputtered in an Ar + N 2 atmosphere, with different substrate biases (0 to −200 V) at various nitrogen flow ratios (N 2 % = 0–5%). The resistivity, composition, crystalExpand
