摘要: Abstract The degree of epitaxy thin sputtered and laser ablated films have been investigated by Raman spectroscopy. Using the selection rules for scattering different phonons in YBa 2 Cu 3 O 7−δ superconducting on SrTiO MgO are found to be epitaxially grown with c -axis perpendicular substrate. On ZrO also grow their substrate, but randomly oriented a / b -directions plane film.
