Influence of the morphology of Barium Strontium Titanate thin films on the ferroelectric and dielectric properties
Abstract
In the present study, Ba0.8Sr0.2TiO3 thin films were realized by chemical solution deposition and spin-coating on stainless steel substrates using the classical multi-layer technique. In order to influence the morphology of the films, three solutions with a different concentration, 0.1 M (BST0.1M), 0.3 M (BST0.3M) and 0.6 M (BST0.6M), were prepared. The dilution is shown to influence the grain size of the films and as consequence also its ferroelectric and dielectric properties.
