Towards understanding the defect properties in the multivalent A-site Na${}_{0.5}$Bi${}_{0.5}$TiO${}_3$-based perovskite ceramics

Pengcheng Hu, Chinmay Chandan Parhi, Jurij Koruza +1

A defect model involving cation and anion vacancies and anti-site defects is proposed that accounts for the non-stoichiometry of multi-valent $A$-site Na${}_{0.5}$Bi${}_{0.5}$TiO${}_3$ b…
