Abstract :
Several articles report two-layer c-axis heterostructures of Bi4Ti3O12 on BiSrCaCuO. However in some applications, or for integration purposes, multi-layer geometries composed of alternating c-axis or non c-axis thin films might be useful. From this perspective we investigated growth of c-axis and non c-axis BiSrCaCuO on Bi4Ti3O12 structures. The paper mainly focuses on evaluation of the structures from the growth, stability/interdiffusion, uniformity/morphology points of view based on structural and microstructural data.
