Notes:
We measured transmittance and reflectance spectra of commercial SrTiO3 crystals in the infrared region (25–12 000 cm−1). The reflectance R(ν) spectra confirm recent results. The transmittance T(ν) spectra show that SrTiO3 is transparent above 1000 cm−1, while the model usually employed to describe the complex dielectric function of SrTiO3 predicts a negligible transmittance in all the infrared region. By combining T(ν) and R(ν) spectra, we directly determine the frequency dependence of the refractive indices n and k which accounts for the spectra measured in the mid-infrared and near-infrared range. This result will be important for a correct analysis of the infrared spectra of films deposited on SrTiO3. © 1996 American Institute of Physics.
