Mixed ionic–electronic conduction and defect chemistry of (Na_0.5Bi_0.5TiO₃)_1−x(BiCoO₃)_x (0 ≤ x ≤ 0.06) solid solutions

Abstract

The electrical conductivity of Na0.5Bi0.5TiO3 (NBT)-based materials has been investigated intensively in the past decade, however, the conduction behaviour with incorporation of variable-valence elements has been limited. Here (NBT)1-x(BiCoO3)x (NBT-BC,...
