K. Kanehori et al., LOW-TEMPERATURE GROWTH OF HIGH-T-C SUPERCONDUCTING FILMS BY PLASMA-ENHANCED METAL-ORGANIC CHEMICAL-VAPOR-DEPOSITION, Phase transitions, 42(1-2), 1993, pp. 111-115
Plasma-enhanced MOCVD in which metal-organic compounds are sublimated
directly into the growth chamber is studied for the first time as a ne
w low-temperature process for growing superconducting YBa2Cu3O7-x thin
films. Y(THD)(3), Ba(THD)(2), Cu(THD)(2) and oxygen are used as metal
sources and oxydizing agent. Emission spectroscopy reveals that activ
ated metal-organic compounds and activated oxygen species are present
during film growth. Superconducting YBa2Cu3O7-x films whose zero-resis
tivity temperature are 50 K and 82 K are grown at 550 degrees C and 60
0 degrees C.
