“…Large electric fields (0-400 kV/cm) can be achieved in thin film BST (224 nm) using low voltages [2]. For ferroelectric BST film, the tunable properties are most researched in the microwave region and in the terahertz range by the means of dc electric-field [8,9,10], or by the means of codoping and adjusting sintering temperature for attain the high modulation of Ba0.67Sr0.33TiO3 ceramics [2], or adopted the method of temperature control [2]. Due to the excellent optical performance, many properties of the film have been experimentally and theoretically studied [11].…”

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 30 V. And the results are attributed to the soft mode hardening caused by the electric field.

The absorption tunability of 100 nm thickness of ferroelectric Barium Strontium Titanate (Ba 0.5 Sr 0.5 TiO 3) thin films with different densities of pumped optical field is measured by terahertz time-domain spectroscopy in the range of 0.2 THz-1.2 THz at 19℃. Experimental results show that the absorption coefficient of BST film is approximately at 5000 cm −1-20000 cm −1 in the range of 0.2 THz-1.2 THz and the absorption coefficient reached up to 16% when we applied the optical field up to 600 mW. The theoretical calculations reveal that increasing photoexcitation fluences is responsible for the increasingof transmission change in the conduction current density cause the absorption coefficient varied.
