Abstract

Low-temperature growth of YBa2Cu3Ox films by CVD has been investigated using Y (DPM)3, Ba (DPM)2 and Cu (DPM)2 as starting materials and N2O as an oxidizing agent. 123-perovskite structure has been prepared at a substrate temperature of 530°C. Superconducting films with zero-resistivity Tc of 15K and Tonset=87K has been obtained at Tsub=610°C and Tc=83K, Tonset=89K at Tsub=650°C. A 254nm-light has promoted decomposition of β-diketonate complex at Tsub=215°C.
