Which outcome results when rapidly annealing a polycrystalline silicon film?

A)Increased grain size occurs.
B)Reduced carrier mobility results.
C)Higher defect concentration forms.
D)Amorphous structure remains stable.

💡 Explanation

Rapid annealing causes grain growth because of increased atomic mobility and the recrystallization mechanism, reducing the total grain boundary area, therefore grain size increases, rather than reductions in mobility or increased defects due to the driven increase in crystalline order.
