← ScienceWhich outcome results when oxygen vacancies increase significantly in a perovskite crystal lattice?
A)Increased electronic conductivity occurs✓
B)Reduced thermal expansion coefficient
C)Enhanced piezoelectric charge generation
D)Elevated mechanical stress resistance
💡 Explanation
Increased oxygen vacancies cause increased conductivity because they introduce electron holes into the lattice via the mechanism of **doping**. Therefore conductivity rises, rather than other properties being affected, because electronic band structure changes.
