Abstract

This letter reports and discusses the observation of sol-gel solid phase epitaxy (SPE) of (110) Pb_0.99Nb_0.02(Zr _0.52Ti_0.48)_0.98O₃ or PNZT(2/52/48) on 3 in. diam (011̄2) sapphire. The epitaxial nature (with at least single crystal-like texture) of these films was ascertained by HRTEM and x-ray diffraction studies, including pole figure analysis. Such PNZT thin films (0.6 μm) were transparent to wavelengths between 0.4 and 5.6 μm, and exhibited an optical band gap and a refractive index (at 0.6328 μm), of 3.6 eV and 2.5-2.6, respectively.
