Electronic Origin of Non-Zone-Center Phonon Condensations: Octahedral Rotations as A Case Study

Autor: Yoshida, Suguru, Akamatsu, Hirofumi, Hayashi, Katsuro

Unstable zone-boundary phonon modes drive atomic displacements linked to a rich array of properties. Yet, the electronic origin of the instability remains to be clearly explained. Here, we propose that bonding interaction between Bloch states belongi

Ferroelectricity of Dion-Jacobson layered perovskites CsNdNb$_2$O$_7$ and RbNdNb$_2$O$_7$

Autor: Asaki, Sota, Akamatsu, Hirofumi, Hasegawa, George, Abe, Tomohiro, Nakahira, Yuki, Yoshida, Suguru, Moriyoshi, Chikako, Hayashi, Katsuro

Crystallography and dielectric properties in Dion-Jacobson layered perovskites, CsNdNb$_2$O$_7$ and RbNdNb$_2$O$_7$, have been examined in dense polycrystalline samples, and polarization hysteresis loops that substantiate ferroelectricity have been o
