Polarized structured nitrides semiconductors become attractive for they possess unique electronic properties with environment friendly. The stability, ferroelectricity, photocatalytic and photovoltaic properties of super-wurtzite Mg2XN3 (X= Bi, Mo, Nb, Sb,...

Li2SbBiO6 slightly improves the ferroelectric polarization of LiSbO3 and significantly reduces the band gap to expand its applications in photovoltaic and photocatalysis under visible light.

CaBiO3 under tensile strain can maintain high ferroelectric polarization strength and strong visible light absorption ability, further promoting photocatalytic hydrogen production.
