← ScienceWhich consequence arises when excessive thermal vibration weakens adhesive molecular bonds?
A)Increased creep rate observed✓
B)Reduced electromigration occurrence there
C)Enhanced passivation layer formation
D)Increased piezoelectric coefficient measured
💡 Explanation
Increased creep rate results because thermally activated bond breakage via Arrhenius equation facilitates atomic movement; this is called Atomic diffusion. Therefore, creep increases rather than reduced electromigration because electromigration is driven by electron flow.
