Resonant Excitation of the Ferroelectric Soft Mode by a Narrow-Band THz Pulse

Resonant Excitation of the Ferroelectric Soft Mode by a Narrow-Band THz Pulse

This study investigates the impact of narrow-band terahertz pulses on the ferroelectric order parameter in Ba<sub>0.8</sub>Sr<sub>0.2</sub>TiO<sub>3</sub> films on various substrates. THz radiation in the range of 1–2 THz with the pulse width of about 0.15 THz was...
