Abstract

Effects of Fe/Si ratio and growth temperature were investigated in order to realize high quality Fe3Si/Ge structures. It was found that very small Xmin values (2-3%) were achieved in a wide temperature range of 60-200°C under the stoichiometric condition. From TEM observation, it was rvealed that the Fe3Si/Ge structures with atomically flat interfaces were realized. In addition, thermal stability of the Fe3Si/Ge structures was guaranteed up to 400°C. These results suggested that growth at a low temperature (<200°C) under the stoichiometric condition was essential to obtain high quality Fe3Si/Ge structures with sharp interfaces.
