Crystallographic and Electrical Properties of Barium Zirconium Titanate Doped by Indium and Lanthanum

Abstract:

Barium Zirconium Titanate (BZT) films doped by Indium and Lanthanum were prepared using Chemical Solution Deposition followed by spin coating method. After deposition, the spesimen was annealed at 800 °C for 3 hours, using 3000 rpm angular spin coating speed. From crystallographic examination we found that the system is perovskite tetragonal with lattice parameters of a = 3.967 Ǻ, c = 3.988 Ǻ. On adding Indium and Lanthanum dopants, their lattice parameters have slightly increased. The spontaneous polarization of BZT is 23.13 µC/cm², and their spontaneous polarizations increase on adding La dopant. The best spontaneous polarization is at 1 mol % dopant of Lanthanum.
