Abstract

PbZr_0.4Ti_0.6O₃/La_0.5Sr _0.5CoO₃ heterostructures have been grown on Pt/Ti/SiO ₂/Si substrates by chemical solution routes. Optical properties of the PbZr_0.4Ti_0.6O₃/La_0.5Sr _0.5CoO₃ heterostructures were studied by infrared spectroscopic ellipsometry (IRSE) in the spectral range of 2.5-12.5 μm. The optical constants of PbZr_0.4Ti_0.6O₃ and La _0.5Sr_0.5CoO₃ thin films were determined by fitting the IRSE data using a classical dielectric model and a Drude dielectric model, respectively. For PbZr_0.4Ti_0.6O₃ thin films, the refractive index decreases and the extinction coefficient increases as the wavelength increases. For La_0.5Sr_0.5CoO ₃ thin films, the refractive index and the extinction coefficient increase as the wavelength increases. The absorption coefficient of La _0.5Sr_0.5CoO₃ thin films is greater than 10 ⁴ cm^-1 for the wavelength range of 2.5-12.5 μm. The absorption coefficient of PbZr_0.4Ti_0.6O₃ thin films on a La_0.5Sr_0.5CoO₃/Pt/Ti/SiO ₂/Si substrate is smaller than that on a Pt/Ti/SiO₂/Si substrate by a factor of two.
