← ScienceWhich outcome occurs when dopant segregation contaminates recrystallization?
A)Reduced carrier mobilities materialize thereafter✓
B)Substrate temperature remains ultimately homogenous
C)Crystal quality improves substantially later
D)Lattice vacancies decrease gradually onwards
💡 Explanation
Reduced carrier mobility occurs due to increased scattering because dopant segregation creates localized regions of high impurity concentration, causing increased electron scattering; therefore, mobility decreases rather than temperature homogenization or vacancy decreases as the crystal lattice disorders.
