Outline of Final Research Achievements

Ferroelecrics polarized by electronic polarization draw attentions of researchers. We have claimed that an organic conductor α-(BEDT-TTF)2I3 and its relatives are the matters exemplifying the idea of the novel class of ferroelectrics. In the present research, we performed dielectric constant measurements of α'-(BEDT-TTF)2IBr2 for radio frequency, and pyroelectric current measurement in α'-(BEDT-TTF)2I3 using an ac method by modulating sample temperature.
