The origin of hyperferroelectricity in LiBO(3) (B = V, Nb, Ta, Os)
The electronic and structural properties of LiBO(3) (B = V, Nb, Ta, Os) are investigated via first-principles methods. We show that LiBO(3) belong to the recently proposed hyperferroelectrics (hyperFEs), i.e., they all have unstable longitudinal optic phonon modes. Especially, the ferroelectric-like...
