摘要

Infrared optical characterization of single crystal SrTiO3, an important substrate for high-Tc superconducting films, had been studied by transmission and reflection measurements. We measured absorption spectrum of this crystal, from 50 - 5000cm-1and 80 - 300 K. This crystal has highly reflectivity behavior in far-infrared (FIR) range. The vibration modes of this crystal are clearly shown temperature dependent behavior. The main absorption dips of FIR reflection measurements are shown in 170, 483 cm-1 at 80 K. These dips have 3 cm-1 shift at temperature from 300 K down to 80 K. In addition to this main dips, there is another dip appeared at 441cm-1 when the temperature down below 100 K. This feature did not show in previous reports. The vibration modes of this crystal substrate, as well as dielectric behaviors that are important characters for analyzing superconducting films will go further studies.
