WebFeb 14, 2024 · Here, we have investigated the sputtering/annealing technique for the growth of CaxCoO2 (x = 0.33) thin films. In this approach, CaO–CoO film is first deposited by rf-magnetron reactive cosputtering from metallic targets of Ca and Co. Second, the as-deposited film is reactively annealed under O2 gas flow to form the final phase of CaxCoO2. highrise advantage vs cftcWebMay 21, 2008 · Silane (7803-62-5) is a highly inflammable, pyrophoric, and reactive gas that constitutes a significant fire and explosion hazard.
