  • Abstract
    The terahertz dielectric properties of several heterostructures based on epitaxial SrTiO3 and DyScO3 thin films were characterized without and under applied static or low-frequency electric field. We demonstrate up to 65% variation of the permittivity of SrTiO3 films and up to 35 % modulation of the power transmission of terahertz waves at 500 GHz and 112 V (75 kV/cm) bias.
