文摘
- •
Good dielectric temperature stability was found in BiAlO3-doped (Na, K, Li)NbO3.
- •
Dielectric anomaly of ferroelectric–paraelectric transition was suppressed.
- •
High-temperature dielectric relaxation was attributed to oxygen vacancies.
- •
Ea is associated with both oxygen vacancy concentration and lattice parameters.
