| Outline of Final Research Achievements |
Bulk photovoltaic effect in the ferroelectric liquid crystals was studied. The photovoltaic effect was proportional to the spontaneous polarization and carrier mobilities of the ferroelectric liquid crystals. The photovoltaic effect was generated by the internal electric field based on spontaneous of the bulk of the ferroelectric liquid crystal phase, unlike conventional photovoltaic effect produced at the interfacial junction. The fact that this photovoltaic effect was observed only in enatiomeric but not in racemic samples indicates that this effect is originated from molecular chirality.
