Anisotropic dielectric response of lead zirconate crystals in the terahertz and infrared range at low temperature

Polarized terahertz transmittance and infrared reflectivity measurements were performed on selected lead zirconate crystals at T = 10 K. The fit of the spectra enabled us to obtain all three principal components of its anisotropic dielectric function and the corresponding parameters of the polar pho...

Summary:Polarized terahertz transmittance and infrared reflectivity measurements were performed on selected lead zirconate crystals at T = 10 K. The fit of the spectra enabled us to obtain all three principal components of its anisotropic dielectric function and the corresponding parameters of the polar phonon modes.
