摘要: As-grown thin films of YBa2Cu3O7-y with a smooth surface were obtained on lattice-matched NdGaO3 substrates by ArF laser ablation deposition. The as-grown film has zero-resistance temperature (Tc) at 90 K. full width half-maximum (FWHM) the X-ray diffraction peak (005) was as narrow 0.12 degrees. These results suggest that high-quality single crystals. are thought to be promising substrate for epitaxial growth high Tc films.
