Abstract :
Time-domain THz spectroscopy is used for investigation of electric field tunability of the dielectric properties of SrTiO3 crystals at temperatures from 90 to 293 K. The low-frequency polar phonon in SrTiO3 is shown to be responsible for the electric field dependence of dielectric properties.
