Electronic Origin of Defect States in Fe-Doped LiNbO3 Ferroelectrics by Yuji Noguchi, Ryotaro Inoue, Masaru Miyayama

“…We show that Fe2+ on the Li site (Fe2+Li) features a displacement opposite to the direction of spontaneous polarization and acts as a trigger for the bulk photovoltaic (PV) effect. In contrast to Fe3+ on the Li site that forms the defect states (1e, a, and 2e) below the conduction band minimum, the reduction from Fe3+ to Fe2+ accompanied by a lattice relaxation markedly lowers only the a state (dz2) owing to a strong orbital hybridization with Nb-4d. …”
