Аннотация

Активно ведется разработка новых керамических материалов, которые обладают ионной проводимостью и могут быть использованы в качестве компонентов в различных электрохимических устройствах. Это исследование сосредоточено на изучении электропроводности полученного недавно слоистого перовскитоподобного оксида La2BaLu2O7, обладающего двухслойной структурой Руддлесдена-Поппера. Соединения с данной структурой проявляют ионную проводимость, уровень которой зависит от замещений в кристаллической решетке. Было установлено, что электропроводность в La2BaLu2O7 имеет смешанный кислородно-ионный характер, при этом ионная проводимость составляет в среднем 66.5% от общей проводимости.
