ENHANCED PURITY OXIDE LAYER FORMATION

摘要

Methods for producing high quality oxide layers for use in various applications, especially epitaxial rare earth oxide layers as buffers (16) for high temperature superconducting layers (18) formed on bi-axially textured metal subsrates (12) are disclosed. The oxide layers have complete coverage of grain boundaries, and reduced levels of carbon contamination, while retaining excellent biaxial texture. Particular control over oxidation potential of processing atmosphere and heating steps lead to improved oxide layers.
