摘要：

Using near IR (lambda = 1.0-mu-m +/- 10 nm) transmission microscopy with computational absorption analysis, the effects of axial magnetic fields on micro- and macrosegregation during LP-LEC growth of GaAs were quantitatively investigated with a spatial resolution of approaching 2-mu-m. Segregation inhomogeneities exceeding one order of magnitude are found to be related to fluid dynamics of the melt. The applicability of the BPS theory as well as the non-applicability of the Cochran analysis are established.
