Abstract

A significant decrease in the dielectric loss and leakage current by introducing Ce in small amounts into BST thin films is demonstrated. The other effects of Ce doping are a lowering of the dielectric constant and a lower temperature coefficient of dielectric constant. In films containing a periodic fluctuation of Ce concentration through the thickness, prepared using a multilayer approach, the dielectric loss is further reduced. The periodicity of the composition is shown to have a significant effect on the properties. The properties of the multilayer films are seen to be significantly different from the single layer films of corresponding average composition.
