抄録

We present the use of Raman spectroscopy as a rapid and convenient evaluation tool for domain distribution of tetragonal PbZrxTi1−xO3 (PZT) thin films. From polarized Raman analyses of epitaxial PZT thin films with various c-domain volumes, we found that the intensity of the A1(TO) modes linearly scales with the c-domain volume. These observations, as well as the quick and nondestructive characteristics of this technique, clearly imply that Raman spectroscopy has enormous potential to quantify the fraction of c-domain volumes in a wide range of PZT devices.
