| Research Abstract |
In this research, we noticed TTF-CA crystal that shows ferroelectric transition and controlled the ferroelectric nature, constructing a system of THz spectroscopy. Using the THz system, we investigated temperature dependence of transmittance spectra in TTF-CA in the THz region and could probe variation of the THz signal after illuminating femtosecond laser pulses of 800 nm.
