Ferroelectricity in thiourea SC(NH2)2

We calculate the molecular polarizability in the ferroelectric state from the refractive indices (n a =1.789, n b =1.643, n c =1.806). We adopt the rigid dipole model and make a model for the potential energy, where the dipole interaction among the molecules and the rotation potential. The change of...

Description
Summary:We calculate the molecular polarizability in the ferroelectric state from the refractive indices (n a =1.789, n b =1.643, n c =1.806). We adopt the rigid dipole model and make a model for the potential energy, where the dipole interaction among the molecules and the rotation potential. The change of rotation angle and the spontaneous polarization are also discussed.
