Epitaxial growth of YBa2Cu3O7 superconducting layers by chemical solution deposition
We studied the optimun temperature to favor the epitaxial growth of YBa2Cu3O7 layers using threesintering temperatures of 820, 840 and 860℃, by the chemical solution deposition method in SrTiO3[100] monocrystalline substrates. Surface morphology was obtained by optical imaging, which qualitativelych...

| Sumario: | We studied the optimun temperature to favor the epitaxial growth of YBa2Cu3O7 layers using threesintering temperatures of 820, 840 and 860℃, by the chemical solution deposition method in SrTiO3[100] monocrystalline substrates. Surface morphology was obtained by optical imaging, which qualitativelycharacterize the homogeneity and the grain presence along the c-axis. The X-ray diffractionconfirms the preferential epitaxial growth (00l) of the YBa2Cu3O7 crystals, resulting in a higher intensityof the profiles (00l) for the temperature of 860℃. The samples shown superconducting behaviourat critical temperature of 90 K, for the three cases. |
