Which risk increases when the substrate temperature is poorly controlled during thin-film crystal lattice deposition?

A)Increased crystalline domain boundary defects
B)Enhanced diffusion-based dopant homogeneity
C)Maximized film stress crack resistance
D)Reduced metastable polymorph phase formation

💡 Explanation

Increased crystalline domain boundary defects result because film atoms lack sufficient thermal energy to find their optimal positions, thereby causing imperfect lattice formation via kinetic trapping, rather than forming a flawless film; therefore defects are higher, rather than improved domain boundaries or better films.
