摘要：

By combining reflectance spectroscopy and spectroscopic ellipsometry, the complex dielectric function of SrTiO3 in the frequency range 40-5000 cm-1 at 20, 100, 200, and 300 K has been determined. Using a factorized description, analytical expressions for the optical quantities were derived, giving excellent agreement with the experimental data. These can be used for two-layer fits of films on SrTiO3, e.g., of high-T c superconductors. The fit parameters complement very well those found at higher temperatures. © 1995 American Institute of Physics.
