← ScienceWhich outcome is caused when cooling gallium arsenide below its liquidus temperature?
A)Microsegregation affects electrical performance ✓
B)Homogenization fully eliminates crystal defects
C)Increased material ductility is fully prevented
D)Densification occurs without compositional changes
💡 Explanation
As the melt cools, microsegregation of arsenic and gallium occurs because phase changes favour one element over another during initial crystal nucleation. Therefore, resulting compositional gradients alter electrical transport rather than creating homogeneity or preventing ductility, as these require other mechanisms.
