| Abstract | The far-infrared optical and dielectric properties of ferroelectric perovskite titanate powder BaTiO3 are reported. The terahertz time-domain spectroscopy (THz-TDS) measurement reveals that the low frequency dielectric response of BaTiO3 is closely related to the lowest pair of transverse optical (TO) and longitudinal optical (LO) modes near at 180 cm(-1), which is verified by Raman spectroscopy. This result provides a better understanding of the relation of low-frequency dielectric function with the optical phonon mode for ferroelectric materials. Combining terahertz TDS with Raman spectra, the overall low frequency optical phonon response of BaTiO3 is presented in an extended spectral range from 6.7 to 1200 cm(-1). (c) 2007 Elsevier B.V.
