Infrared spectroscopy of an epitaxial BaTiO3/SrTiO3 superlattice grown on a (110) SmScO3 substrate
Original language description
Polarized infrared reflectance spectra of a BaTiO3/SrTiO3 superlattice deposited on the (110) cut of SmScO3 substrate and bare substrate have been studied in the broad temperature range from 10 to 650?K. Strong infrared anisotropy of the SmScO3 substratewas observed and explained as a projection of B 1 u and B 2 u ?+?B 3 u phonons into the (110) plane. In the polarization parallel to the c-axis below 200?cm1, an anomaly in the temperature dependence of the spectra was observed. Fitting the superlatticeand substrate spectra, the parameters of optical phonons and their temperature dependence were determined. The superlattice phonon frequencies show only classical behavior, it means frequency hardening on cooling. Anisotropy was also found in the superlattice phonon frequencies and their contributions to static permittivity.
