Abstract
We investigated the tunability of the dielectric characterization of the Ferroelectric Barium Strontium Titanate (Ba0.5Sr0.5TiO3) thin film on the Strontium Titanate substrate by a dc bias electric field through the terahertz time-domain spectroscopy. The tunability of the real part of the permittivity reached up to 74.8% and the imaginary part of the permittivity reached up to 33.6% when the bias electric field up to 30Â V. And the results are attributed to the soft mode hardening caused by the electric field.
