← ScienceWhich outcome occurs when a pervoskite crystal experiences oxygen vacancy formation?
A)Increased electronic conductivity✓
B)Enhanced mechanical strength
C)Reduced Curie temperature
D)Decreased thermal expansion
💡 Explanation
Increased electronic conductivity occurs because oxygen vacancies introduce free charge carriers via the **charge compensation** mechanism, therefore enhancing conductivity rather than other property changes because electrons become unbound inside the crystal.
