A 6 cm in diameter Ga-doped Ge0.98Si0.02 crystal was grown using the vertic
al Bridgman method with a submerged baffle. After 3 cm of growth, the baffl
e was removed and the solidification continued in conventional Bridgman con
figuration. The composition of Si and Ge was measured using electron probe
micro-analysis (EPMA). The micro-structure pattern was revealed by etching.
The advantages of using the baffle for growth of Si-Ge alloys is discussed
