摘要：

Previous polarized infrared reflectivity spectra of BaTiO3 were unable to show the expected differences between the A1 and E phonons. This can be explained by the small penetration of light polarized perpendicularly to the ferroelectric axis in the LO-TO range of the lowest E phonon, where only the crystal surface determines the reflection of light. We show that with an adequate etching of a mono-domain single-crystal it is possible to obtain good quality spectra for both polarizations. © 1979.
