Raman Spectra of Ultra thin and (001),(110) and (103) Oriented YBa 2Cu 3O 7-δ Films |
| |
| Abstract: | Abstract The quantitative characterization of ultra thin YBa 2Cu 3O 7-δ (YBCO) films, which is difficult due to leakage of spectral features from the substrate, was reported first. By subtracting these features, clean vibrational spectra of YBCO films with thickness down to 12 nm have been obtained. Polarized Raman spectra of (001),(110) and (103) oriented epitaxial YBCO films have been measured and compared with each other. The recorded characteristic Raman spectra demonstrate that the orientation of these epitaxial films can be easily and nondestructively determined. |
