Growth of MgB2 thin films on alumina-buffered Si substrates by using hybrid physical–chemical vapor deposition method

Growth of magnesium diboride thin films on boron buffered Si and silicon-on-insulator substrates by hybrid physical chemical vapor deposition

“…One may also grow MgB 2 on the top of the alloy layer [18]. Lee et al have grown MgB 2 films on Al 2 O 3 buffered Si substrates at low temperatures (500 °C-600 °C) using HPCVD [19]. However, the films grown at lower temperatures showed rough surfaces making it difficult to use for micron-size device fabrication, and some alloy formation was observed even with the low deposition temperature and the Al 2 O 3 buffer layer.…”

Production of MgB2 superconducting coatings by electrophoresis on metal substrates

“…The discovery of 39 K superconductivity in MgB 2 [1] has stimulated extensive research on the production of the material in several forms such as tapes [2], wires [3,4], thin and thick films [5][6][7]. The production of MgB 2 films and wires exhibits difficulties arising from the considerable volatility of magnesium and its high reactivity with oxygen.…”
