Which consequence results when molecular orientation is imperfect during vapor deposition?

A)Reduced thin-film crystallinity results
B)Increased substrate temperature occurs
C)Decreased precursor partial pressure arises
D)Enhanced surface diffusion dominates

💡 Explanation

Reduced thin-film crystallinity results because imperfect molecular orientation hinders the self-assembly process during film growth via changes to surface energy. Therefore, a disordered structure forms, rather than an ordered crystalline structure that requires proper alignment.
