Abstract

Effect of growth temperature on crystalline structure of YBCO thin films have been studied by a MOCVD method using a vertical reactor with a flow guide. At growth temperature between 600°C and 675°C, the films are composed of a mixture of a-axis and c-axis oriented phases, while at growth temperature of 700°C or higher, the a-axis-oriented phase disappears. At these growth temperatures, only c-axis-oriented phases are existing on the films. Film grown at 680°C or higher have the composition of Y : Ba : Cu is 1 : 2 : 3, as confirmed from EDAX spectra. Films deposited at 700°C have critical temperature around 87.4 K.
