Abstract

Dielectric spectra of Barium Titanate under an electric field were investigated by time-domain terahertz spectroscopy. The real part of permittivity was increased with the external field while the imaginary part displayed negligible variations. Besides, tunability of dielectric constant reached to 14.8% when the electric field was tuned to 45 V.
