YSZ/CeO2/YBCO heterostructures grown in-situ by pulsed injection CVD

Abstract
A great improvement of YBCO film properties on YSZ substrates was obtained by a simple in-situ insertion of a thin CeO2 buffer layer between YSZ and YBCO. CeO2/YBCO hetreostructures on YSZ were deposited by a new pulsed injection CVD technique. The CeO2 buffer layer stopped Zr diffusion from the substrate into the film, improved the YBCO film epitaxy and increased Jc up to 4-5.106 A cm-2 at 77 K. The thickness of buffer layers in the range of 20-160 nm had but little influence on YBCO film properties.
