Growth and fundamental properties of GeSi bulk crystals

In this paper, we attempted the Czochralski growth of GeSi bulk crystals of large size in the whole composition range 0 < x <1and succeeded in growing full single crystals of GeSi alloys of large size within the composition ranges of 0 < x < 0.85 < x < 1 . This paper reports the current results on bulk crystal growth of GeSi alloys and on their fundamental properties that are brought about by alloying.
