Low-temperature processing of superconducting Tl2Ba 2Ca1Cu2Ox films on CeO2 buffered sapphire
Tl2Ba2Ca1Cu2Ox thin films with excellent alignment have been grown on CeO2 buffered R-plane sapphire using an ex situ anneal step in argon atmospheres at temperatures of 720-740°C. With this low-temperature process we have overcome the serious problem of reaction layers being formed at the CeO 2/Tl2...
