← ScienceWhich outcome occurs when rapid cooling induces crystallization of amorphous silicon?
A)Trapped point defects concentration increases✓
B)Grain boundary surface energy decreases
C)Long-range phonon scattering diminishes
D)Radiative recombination rate increases
💡 Explanation
The increased density leads to defects; because as crystallization occurs via nucleation and growth, the interfaces trap impurities/vacancies; therefore point defect concentrations increase rather than boundary improvements from annealing or better radiative behavior.
