Abstract

NdScO3 (NSO) is a rare-earth scandate suitable as a substrate application for films of other perovskites. BaTiO3 (BTO), a well-known ferroelectric perovskite, is an interesting material for thin film deposition, as it gains almost no strain with NSO, which makes domain changes at that phase possible to be comprehended in detail. This study investigates different strategies for treating NSO substrates before deposition, relating the quality of their topmost surface with the characteristics of the films deposited on top by means of Pulsed Laser Deposition (PLD). A more in-depth exploration of the steps in the production of films considers all possible factors that contribute to a lack of reproducible epitaxial films, including the quality of the target materials for deposition and the PLD process itself, which rises to the suggestion of using Pulsed Laser Interval Deposition (PLID) to relax the surface between pulses.
