Abstract

A new chemical route using an alkanolamine chelating agent for synthesis of ferroelectric Sr0.8Bi2.3Ta2O9 (SBT) thin films is investigated. The addition of alkanolamine provided stability to the SBT solution by retarding the hydrolysis and condensation rates. This solution could be stored for 30 days without any appreciable change of the properties. The crystallinity and the microstructure of the SBT thin films improved with increasing annealing temperature, and strongly influenced the ferroelectric properties. This alkanolamine modified films annealed at 800°C exhibited low voltage saturation, high remanent polarization and resistance to fatigue after 1010 switching cycles. These electrical properties are favorable for non-volatile memory applications.
