Fragmentation of Faceted Dendrite in Solidification of Undercooled B-Doped Si Melts

The fragmentation of the faceted dendrite of B-doped Si solidified from the undercooled melt was investigated using an electromagnetic levitator. The <110> dendrites, which grew at ΔT <~ 100 K, never fragmented because they were composed of {111} planes with the lowest interface energy. On the other hand, the <100> dendrites, which grew at ΔT >~ 100 K, showing fourfold axial symmetry, broke up into small pieces at undercoolings of more than 200 K. It was suggested that the capillary force acts on the interface with a relatively high energy to break up the dendrite into small pieces, since the <100> dendrites are composed of {110} and {100} planes with ...
