Abstract:
The ultrafast dynamics of electrons and phonons excited by femtosecond light pulses in ferroelectric semiconductor Sn$_2$P$_2$S$_6$ is investigated using the optical pump-probe technique. It is demonstrated that a soft mode can be excited in this ferroelectric in the vicinity of the phase transition initiated by laser radiation.
